amican churches in charleston today. last night both turnedtoheir attentioront-runner sanders. >> i'm a democrat for a simple reason. ( cheers and applause ) i ain't a socialist. icr ain't a plu. i'm a democrat. >> senator sanders believes in inflexible ideological revolution that leaves out most democrats, not to mention most americans. i believe we can defeat trump and deliver for the american people by empoweringhe american people, to make their own health care choic with medicare for all who want it. ( cheers and applause ) >> sreenivasan: for more on the results from the caucus, megan messerly, a reporter for "the nevada independent" joins us now from las vegas. plich is that mr. buttigieg's camign had cnts about irregularities? what were the colaints? >> right. so buttigieg's campaign sent aer

leo the nevada state democratic party just before midnight last nigt letting them know that 3 discovered some irregularitiesnd errors in the results. this is based off of the report that they received from their precinct captain. they said that theree a lot al issues with the trance fer of early voting data into the caucus state process. for instance, they sn some instances they didn't think that early votes were getting cnted during the realignment. there was at least one inswhnce e they say wrong precinct data early vote data was used on caucus day. so they are asking the party right now to release the separation between the in person and the the early vote total so they can go through ansee thousand folks did individually between those t groups but the party tells they are going to continue reporting the way they have been reporting and they don't have any plans to change the reporting process at this time. >> #01: and at the time they were filing this, the results were quite narrow or the margin

was quite narrow between him and mr. biden or vice pren sident bir the second place slot. >> that is correct, and they even, you know, noted that in their letter they in fact asked the party to address the irregularities and correct these errors that they have identified before releasing the final resultsnd they noted that is because it appears to be a close race between joe biden and pete buttigieg, obviously big steaks here for pete buttigieg, he has he isying to prove that able to appeal to nevada's broad divee constituency, so a victory, even second place victory is important for him that's why sort of the immediacy of sending this letter late last flight to the staty. >> so are people considering, tyd this is perhaps a question more for the pare people considering what is happening in iowa, considering a little bit happenconfusion that in nevada, are the people that u spoke to, are they still supportive of the idea of caucuses to do this the way ey are doing it versus just having

a primary? >> right, that was one of the questions that i asked a lot of people yesterday, because there was a lot of elation, a lot of smiles, everyone was so happy at how well this ipad had worked. about the deliberative caucus process so my question was well should we keep asking a caucus and everyone i spoke to told me no, we should definitely switch the caucus went well yesterday but did not go well enough to change their minds abouwthe fact tha should have a primary, a lot of people told me they just felt like it would be easier to have a government run primary with traditional voting, machinoting booths, it just would be eier to ensurite inteof the results. >> we have heard a lot about different constitucies that turned out for bernie sanders. what did you noti when it came to the youer people that were voting? we have seen a lot of support from young folks for bernie sanders. i think the notable thing for us, for me and my colleagues who

were fanning out at voting sites and at events l across the state was how young people support for bernie sander anslated to their family members, we have heard a lot about -- bernie plot of young sanders were sort of to bring along their parents and grandparents and saw quite a few older folks supporting bernie sanders as well which we wery et exacpporting but i think what bernie sanders was hoping he could build thiso prove tha multigenerational, you know, diverse coalition and the entrance polls we have seen seem to sugst he was able to do that. >> all right. megan messerly from the nevadand indet, tha you so much. >> thank you. >> for the latest on the >> sreenivasan: for the latest e, the 2020 presidential r tuesday's democratic debate and the lead-up to the south carolina primary, visit pbs.org/newshour. >> sreenivasan: in china today, s esident xi jinping called the

family and works full time, now had to find resources to help supervise her mom. that involved everything from durinday, to king herselfh her spending the night with her, and she has installed cameras in the house to in remotely. >> you know, even when i leave for the day and somebody elsis coming in my mom doesn't want me to go so that's a heavy burden on me. because my mom will forget. my mom won't remember that she was a little upset with me when i was leaving, but i will. i'll remember that. >> where are you going? >> i'll be right back. go with bella. >> reporter: then last year a newend told king about a facility nearby that has helped make le easier. it's called town square. it's an adult daycare center that looks more like a village set up specifically for people with the early stages of dementia. >> my mom has a place to g she's entertained. she has no idea what, what it really, truly is. which is, it is a daycare center but it's, you know, it's

disguised as disneyland. >> reporter: there's more than a dozen store fronts including a diner, a barber shop, and a store with clothes and jewelry. 9,000 square feet, all designed to look like a small 1950's town. >> reporter: whas the reaction from people who are first coming here, when they first walk in the door? >> i think what we've typically seen is t kind of takes them back a little bit when they walk through the door. they're just not expecting, i ink, kind of, the scale. >> reporter: scott tarde is the c.e.o. of the glenner family provides adult daycare and fepport services to families ed by alzheimer's in california. he says town square glenner's newest daycare center and is the first of its kind fu the nation, y immersive environment approach, referredo in medical literature a"reminiscence therapy." >> telephone booth here. >> reporter: does it work? >> it does. it rings out to the front desk. t reporter: the idea is t even though people with demeia have lost their short term

memoryhey do often remember things from years back, so they will feel olre at ease in time settings like this. sights and sounds from their past. >> even things like having "i love lucy" on thtelevision. >> do you need water? >> reporter: according to tarde, town square, whose staff includes a specially trained social worker and registered nurse, offers services that can be used as a mod for care. in fact, his group has sned an agreement with a for-profit coany to franchise the town square model across the country. >> we group our partipants in small groups. we create this experience where storefronts and they spend time in probablyive or six storefronts out of the 14 storefronts in the day. ives a variety. they can combine and mix based on activities, interests, based on cognitive functioning. >> reporter: they are greeting cards th made? >> reporter: taylor-dwyer especially likes arts and crafts. she makes cards that are on display in the town square department store. and are they for sale?

pe>> well, it s. you can get three, four,ight in there then you can see that through. then you can also do tha and you can go down, la, la, la and come back upgain. >> she's declining. they call it the long goodbye. lethe best thing about theer town square is that,you know, they have her. and it's securand i feel at ease. >> it's a scary disease. is a disease that at this point doesn't have a cure. director of the san diego chapter of the nonprofit alzheimer's association. e says the country needs more programs like town square, which not only help dementia patients but also support their caregivers. by the year 2050, sheays it's estimated the number of americans with d tentia will mohan double to 14 million, putting increasing stress on the healthcare system and those who take care them. >> caregiving can be a long journey.

some people can provide care for 10+ years for someby that's living with dementia. i think for family caregivers, the hardest part is you're remembering your tmily member y were. and here's a person that's changing right before your eyes. and that can sometimes be even harder for a family caregiver as sed to somgine who's care ng that didn't know that person before. >> he's just a darn nice guy! >> reporter: everince 88-year-old ry patterson was agnosed with alzheimer's five years ago, her daughter tanya carr has hehelped look after but working full-time, carr admits, most of the caregiving burden fell on her 82-year old father atwiome. thout town square, she says, their lives would be a lot more difficult. dad probably would have had a heart attack by now. i'm not kidding. because at least he can look forward to days where he has some time to do what he needs to do. we probably would have called, had to call somebody in to help

and it would have been a lot more expensive. >> hi mary. >> hello >> reporter: in fact, the cost at town square, $95 for eight-hours, is less than the average cost ofn-home care. >> are you trying to get away from me? >> repoer: and the setting seems to appeal to her mom who had appeared to be depressed before coming to town square. even when she can't mber what she's done day to day she knows she has fun here. do yoveu un here? >> oh yeah. >> th le goal is sen her anxiety. not have pression, but also help us keep our sanity. so that's what, that's what town square has done for us. >> and she's my baby. >> and i'm her baby. yes, i am. >> my friend, my baby. >>lde shrobably get home and check on dad. >> yes >> reporter: town auare's servic hours are limited though. basically 9-5. carr says it's just a matter of months before her mother will need 24-hour care.

>> do you know what it says? >> i love you beyond measure. >> oh! >> isn't th cute? >> reporter: jacki wyer's alzheimer's has progressed to the point that she recently moved in with her daughter. but kimberlying knows her mom will likely lose the ability to dress, walk, even swallow and eventually need to be placed in a nursing home. >> to put my mom into a artirement home, which is long-term memory it starts off at $10,000 a month, and who has that? >> reporter: as she figures out what she can to keep her mom calm, safe, and happy. ♪ ♪ >> sreenivasan: this past friday marked the 55th anniversary of the assassination of civil rights activist malcolm x.

the 39-year-old was shot and killed while speaking at the audubon ballroomn new york city. three members of the nation of islam were later convicted of his murder, but there have long been doubts surrounding his death. nta new docuy series on netflix, "who killed malcolm x" reveainls newngs and is raising new questions about his murder. ndnewshour wee ivette felicia and series producer phil bertelsen and series historian abdur-rahman muhammad. >>n, reporter: phil bertel abdul rahman-muhammed, thank you so much for joining us. >> thank you for having us. fi>> reporter: st off, before watching this series, i had no idea that there were so many questions surrounding lcolm x's murder. can you briefly outline some of the holes in the story of his killing and whatrirompted this coming together? the production of this? >> well, ever sinc1966, when three men were convictedor the assassination of malcolm x, scholars have always questioned that verdict from the veity of

beginning. >> there might well be one of the assassins still out there hiding in plain sight, gone unpunished, unquestioned and protected to a cerin degree frm, from prosecution. >> reporter: an you know, yore an independent historian, but this happened decades ago and you've spent the better part of your life researching the truth behinx'd malcol assassination. >> yes, correct. >> reporter: many people told you to drop it. >> a lot of people told me to drop it. >> porter: so why was that so central to you, specifically as an african-american muslim? >> well, because i felt a sense of responsibility. as i moved along i accumulated more and more facts andn formatgarding the case. and it became clear to me very early on that, you know, if i didn't continue, it wasn't going to be done. ct jay edgar hoover, the di of the f.b.i., was

definitely afraid of meone like malcolm x. ve>> you know, would have been able to get to the bottom of the story because this type taof case involves documenon and inrviews. you had to go out into the field and talk to people. it'sot something that you could solve merely by studying. you don't see declassified documents d things like that. wiretaps. you had to go out and talk to peop w were still alive, you know. a once that generation passed away, the story would have been lost forever. >> in the 1960's, the f.b.i. launched one of the biggest counterintelligence operations in its entirchistory. >> bk people everywhere today are better with the hycrisy practiced by whites. >> and they kept a very close watch on brother malcolm. >> and if something isn't done, then i'm afraid that you will have a racial explosion. >> reporter: did you get any pushck from folks in the african-american muslim community or local and federal authorities? are there people who didn't want

this series made? >> for sure. i mean, the fact remains that some of the answers that we're seeking in this story are ones to know.ple didn't want others had to push harderore that we persuasive in our argument in ordero get those answers, you know, should say everything the is to be said about wh this has been a widely held secret for gerations now. and we go into the f it's not just one man who killed malcolm x. but, you know, a kind of complicity on the pa of governmental authorities and law enforcement as well. and those are entities tha don't like to be exposed. so, you kn, we had to try to put the pieces together and in order to, you know, have an argument as to who killed malcolm x.

>> this is pbs newshour wkend, suay. >> rorter: and so what can audiences expect to learn from this series? do you actually answer that question of who killed malcolm x? >> yes, we do. it's really pulled back the veil on this historic crime, that was really an open wound, really in no at just tican-american community, but the world community. and, you know, the fundamental undeg rstand who pulled that shotgun, who were involved. yes, we answer that question. >> i thi we go beyond that question as well. i think we not only look at who killed malcolm x, t who did it and who was malcolm x is also a big part of the story. i think if you begin to ask yourself that question, who killed him? you want to know why. you know, what did he represent that tmade him such a thret

caused so many forces to align against him. >> you seem to be diveatisfied withthing. just what do you want? >> i'm not dissatisfied with everything. i'm just telli you that the negroes themselves would take whatever steps necessary to defend hielf. >> he was a powerful, galvanizing figure for many. and he posed a threat to the stat quo in such a way that people felt he had to be aiminated. so you learn a lut malcolm you may not have already known. and you also learn that two men, it's our belief, wento prison for 20 years f a crime they did not commit. this crime. and as a result of the work that we did in the series and the evidence that we show, the manhattan d.a.'s office has decided to take a preliminary look at whether not this case is worth reopening. >> relsporter: phil ber. abdul rahkman-muhammed, thank you so much for joining us. >> oh, thank younkso much. >> tfor having us, a pleasure.
