>> ninan: the moment when elizabeth became queen of england. this is the "cbs weekend news." >> ninan: good evening. i'm reena ninan. a new confidential memo from the president's lawyers explains why president trump may not be forced to testify before the special counsel. this comes as the president and his team are preparing for a historic summit with north korea. errol barnett has the latest >> reporter: while at camp david, president trump tweeted "there was no collusion with russia," asking, "is the special counsel justice department leaking my lawyers' letters to the fake news media?" shortly thereafter, "the new york times" posted what it describes as a confidential, 20- page document from the president's legal team in january, responding to special counsel robert mueller's questions. john dowd and jay sekulow provide the outline of a potential defense, should the sitting president be compelled to testify.

they suggest, as president "mr. trump cannot obstruct justice since he has the authority to terminate the investigation and use his pardon powers if he so desires. they also implied corruption within the f.b.i. triggered the russia probe and say, "the president is not readily available to be interviewed." >> i don't think he's going to mueller is creating his mueller is creating his own problems. >> reporter: speaking to reporters last week, the president's newly appointed lawyer, rudy giuliani, railed against the inquiry and pushed mueller to make his findings public. >> interview or no interview, by september 1, the public should have an explanation of what mueller has. i really want that because i don't think he has much. >> i think you're going to have a very positive result in the end-- not from one meeting. >> reporter: president trump is currently preparing for a newly revived one-on-one meeting with north korean leader kim jong-un, taking place in singapore june 12. his lawyers have argued the ongoing russia investigation is a distraction from the president's important work.

now, president trump's legal team also admits for the first time that mr. trump "dictated a short, but accurate response," to questions about the trump tower meeting before the election, which found members of his campaign with a russian informant. the response said adoptions were the focus of that meeting, when it was really about getting dirt on hillary clinton. the white house is not responding to the release of this memo, instead referring us to president trump's outside counsel. reena. >> ninan: errol barnett following a lot of news at the white house this saturday evening. thank you, errol. well, cutting-edge science may have solved a decades-long cold case. the so-called golden state killer, wanted for dozens of attacks and at least 13 murders eluded capture for decades. but investigators got his d.n.a. then and now. kenneth craig explains how. >> reporter: suspected serial killer joseph deangelo may have been able to pull off one of the

most notorious killing sprees in california history. but for a former police officer, who eluded investigators for decades, his recent capture came down to modern-day forensic technology. d.n.a. evidence he left behind. more than 100 pages of heavily redacted court documents read like a real-life c.s.i., revealing that a d.n.a. sample recovered this april sealed the case against him. retired n.y.p.d. cold case homicide sergeant, joseph giacalone. >> i think this was the last thing that was on deangelo's mind was that the changing of forensics would ever-- they would ever catch up to him. >> reporter: 72-year-old deangelo has not entered a plea. his alleged crime spree included at least a dozen murders and more than 50 attacks and sexual assaults in the 1970s and 80s. investigators first narrowed in on the so-called golden state killer by plugging d.n.a. from a 1980 double murder into a genealogy website, finding family members, which led to him. with a suspect at their

fingertips, this spring they followed him to a sacramento- area hobby lobby store, and took a d.n.a. sample from his car door handle. days later, investigators recovered another d.n.a. sample from a discarded tissue outside deangelo's home which registered a match to d.n.a. evidence left at one of the crime scenes. >> if you put a trash up on the on the curb, throw cigarette on the floor, that's called abandoned property, and the police can come and collect it and they can test it and use that against you. >> reporter: that evidence is part of a mounting case against deangelo. investigators also searched his home but a judge is not letting the public see what they found inside, ruling the release would make it impossible to get a fair trial. dozens of personal items, including rings and photographs were stolen from the victims' homes, reena. >> ninan: a lot of police work here, kenneth. >> reporter: and investigators have been working to solve these cases for more than 40 years.

>> ninan: kenneth craig, thank you very much. in new mexico, firefighters are battling two big wildfires. dry, hot conditions are fanning the ute park fire to the north and the buzzard fire in the gila national forest. the ute park fire is uncontained. it has forced residents in a nearby town to evacuate. the buzzard fire has also burned around 27,000 acres and is about 40% contained. in hawaii, molten lava destroys more homes. police have been ordered to arrest people who refuse to evacuate. already thousands have been forced to flea to safety, and the relentless volcanic activity has hurt one of the big businesses on the big island-- tourism. here's carter evans. >> reporter: with the latest river of molten rock burning a new path to the ocean, people in nearby kapoho have spent last three days packing up their homes. the lava has now cut off the last road to their community. in leilani estates, rob and christy marin want to stay as long as possible, but with a lava fountain four blocks away from their home... you're not

spending your nights here. >> no, we're not, we're too scared for that. we're in our car in a parking lot. >> reporter: the lava zone is becoming increasingly dangerous. this is the most active fissure right now. we have been watching this one go for days. at times it has been blasting lava up to 250 feet in the air. longtime residents say they knew it was a risk when they bought here. heath dalton was drawn by low home prices. what do you think the next month is going to look like? >> unfortunately, you're looking at it. everyone says a once-in-a- lifetime event. unfortunately, it was in our lifetime. >> reporter: now the dramatic images broadcast around the world are having another impact, on tourism. >> it was kind of a shocker for us because this is really a normal occurrence. >> reporter: ross birch is with the big island's visitors' bureau. he says the eruption impacts less than 1% of the island, but still hotel bookings are down 50%.

even in kona, on the other side of the island. so, do people need to worry? >> oh, absolutely not. if you have plans to come to hawaii, definitely keep those plans. >> reporter: this is highway 137, and lava across the road beyond this police checkpoint here, authorities have been warning for days that this would warning for days that this woul happen. and now they say they might not be able to respond to calls for help from anyone who may have remained inside. reena. >> ninan: carter evans, thank you. hurricane season officially started yesterday, and puerto rico still hasn't fully recovered from last september's hurricane maria. well, this week, the puerto rico department of health released mortality statistics revealing how many people the government says died in september of last year when hurricane maria made landfall until the end of the year. david begnaud is in san juan. david, can you tell us exactly what we know about these new numbers? >> reporter: reena, before we get to the numbers, if i may, let me just show you what is behind me. if there is a memorial to the victims of hurricane maria, this would be it. and it went up about 24 hours ago, right in front of the capitol here in san juan. these are shoes with names inside of them, honoring the

people who died, whose names are not yet factored into the government's official death toll, which is just 64. about those numbers: there was a notable spike in the number of deaths in september of 2017, and an even larger spike in october of 2017. and when you do the math and you compare september, october, november, and december of 2017, it is higher than the year previous in that same time period. the government's death toll is 64, and very few people believe that number, including the governor, who has acknowledged, look, we know the number is going to go higher. he insists they didn't release this information prior to this time period because there are privacy laws. but, reena, this all came to a head this week after harvard university released that study estimating that upwards of 4600 people died because of the storm. now i want to let you know this- - there's a wide range in that study that estimates the number could be as low as 800 or as high as 8,000. but the bottom line is there is no study out to date that puts

the number anywhere near the government's toll. >> ninan: so what does the harvard study ultimately say about those people who died after the storm? >> reporter: that they died because of a lack of access to medical care. but let me say this about those numbers, nina. this is more than just about a shocking headline regarding a number. fema will actually pay to settle funeral deaths for family who can prove they died because of the storm. but this is an acknowledgment for families here that in fact their loved ones were killed by is this hurricane. >> ninan: david begnaud on the ground in puerto rico. children up to eight years old spend an average of two hours and 19 minutes in front of a screen every day. and 47% of parents worry that their kids are addicted to mobile devices. it also includes many parents in the tech industry. jamie yuccas takes a look at how they're dealing with their kids. >> reporter: in silicon valley, devices are an essential part of daily life, but many of the tech

titans parading these products choose to power down when they leave the office, following industry giants like bill gates and steve jobs, who restricted their own kids' access to technology at home. pierre laurent has worked for companies, including microsoft and intel. he says the tech industry designs products to hook users. do you think the average parent is aware of that danger? >> no, i don't think the parents are aware of that. >> reporter: pierre and his wife, monica, became concerned that their three children would miss out on real-life experiences while on their devices. researchers are still learning more about how technology affects kids, but some early studies of heavy tech users show potential links to a rise in teen suicide rates, addiction, anxiety, and loss of social skills. none of the three children played video games or watched tv, and they didn't get cell phones until they were teenagers. their 13-year-old daughter, maia, spends her free time knitting and playing in the backyard. do you ever miss technology? >> not really, no.

the only thing i might miss technology for is listening to music or an audio book. >> every parent is really struggling with how to reap the benefits of technology while minimizing some of the risks. >> reporter: caroline knorr is the senior parenting editor for "common sense" media, a nonprofit that studies the effect of media and technology on kids. they recommend paying close attention to kids' demeanor while using their devices and creating a schedule with guidelines on the types of tech activities they can do and for how long. for monica and pierre, the hope is that a tech-free childhood will lead to more balance later in life. >> >> young children need to grow in a different environment that doesn't have that much technology in it. >> reporter: jamie yuccas, cbs news, silicon valley. >> ninan: coming up, towns across america finding unique ways to attract workers and stop the brain drain. and close call-- a plane weaves through traffic after making an emergency landing. landing.

st. clair, michigan would pay him to move home. they're going to help you with your students loans, right? >> right. >> reporter: and in return you're not going anywhere else. you're basically coming back home. >> exactly, exactly. they're investing a lot of money into me and so i'm looking to invest that back in the community and set up a practice or work out of another practice. >> reporter: skinner is taking advantage of st. clair's "come home award." skinner will get up to $15,000 towards his student loans, just to return. >> you want a treat, baby? >> reporter: it's a deal kayla parzynski couldn't pass up. her $10,000 scholarship paid off her undergraduate loans, which helped her buy her first house. >> it was a great opportunity financially. it took a big load off of me and i think it's worth it. >> reporter: can you see yourself here a long time? >> yeah, i can definitely see myself here for a long time. >> reporter: st. clair county runs along lake huron and the st. clair river, a quiet county

with plenty of small-town appeal. the average annual salary here is just under $52,000, slightly more than the national average. why are you having to pay people to come here? to come herit seems ironic to think that. >> reporter: randy maiers helped create the come home award and works with local business and organizations to help fund it to reverse a brain drain from the area. >> i think a part of it is that the young people that grow up here, they get a chance to leave after high school and go to college, and they want to get away from small-town america. you know, i can't blame them. the lure of detroit or chicago nearby or the carolinas. it draws people away. >> reporter: less than 18% of st. clair's 160,000 residents have a college degree. compare that with nearby washtenaw county, home to university of michigan, where more than half have a college degree. it's not a jobs problem. >> this is worth it. >> reporter: linkedin editor at large chip cutter says the issue is educated and trained workers.

>> so we're seeing this real trend across the u.s. where places like new york or san francisco or boston, these cities that just keep attracting the type of educated workers that employers crave. it's kind of a "rich get richer" situation. >> reporter: it's why incentive programs are popping up around counties, towns, and small cities across america, like crawford county, ohio, grant county, indiana, and the small town of marne, iowa. the movie version of this is the plant closes down and the town shrivels up and dies. that's not exactly what we're seeing here. >> that's right. it tends to be more of a gradual problem where over time workers leave. they don't necessarily come back. a town loses its population, and then the companies that are there say, "we're having a really tough time finding workers." it might not be as dramatic as the hollywood story but it's just as urgent. >> ninan: don dahler reporting. still ahead on the "cbs weekend news," from intensive care to the mount. white sox pitcher danny farquhars' miraculous comeback. e sox pitcher danny farquhars' miraculous comeback.
