i'm aaron gilchrist at the live desk. we now have been able to get some photos. before i show them to you, these are pictures provided by the ferguson, missouri, police department from what they described as a strong-arm robbery at a convenience store this past saturday.

they say the person you see involved in this incident is michael brown, the young man who was shot to death by a police officer in ferguson on saturday. at this point we can tell you that the pictures did in fact come from the police department, they are from surveillance video that comes from a convenience store but at this point we don't know all the specifics behind what exactly police are saying this is in relationship to. so we know this happened before the shooting and that a description went out over the police radios and that the officer involved in the shooting of michael brown says that he encountered someone who fit the description that went out on the radio. the person you saw in the surveillance photos that we just showed you there. so this obviously is still a developing story. the missouri governor does plan to hold a news conference at noon today. we'll make that available to you at nbcwashington.com and we understand the police chief in ferguson will also hold another news conference to answer some questions later on this afternoon. that's the latest from the live desk, back to you. right now an interstate in tennessee is shut down after a

grocery stores as a provider. they say their computer network was hacked at some point in july and it was possible that information including account numbers, expiration dates and the names of customers could have been compromised in this hacking that affected their payment system. at this point there is no evidence, super value says, that any of that information has actually been used but out of an abundance of caution they want to let their customers know there has been a possible data breach and information could have been compromised as it relates to debit cards, credit cards that may have been used this their stores. they work with the shopper grocery stores in our area, many of them in northern virginia and parts of maryland as well. that's the latest from the live desk. barbara, back to you. right now a recall. mccormick brandish you had a recall of ground oregano. this affects 0.75 ounce bottles with the best by dates of august 21st and august 22nd.

they need. >> they don't often have words for things that happen and when they play it out they don't have to have words. >> reporter: cindy bridgeman is the clinical director at safe shores, the only child advocacy center in d.c. it is a place where children go to tell their stories and therapists work to counsel these young victims. >> here they will demonstrate making dinner and they'll make dinner for us sometimes, but sometimes this is where they'll talk about how they didn't have enough food, or how pots and pans went flying through the air when mommy got angry. >> reporter: a majority of children who come through safe shores are victims of sexual abuse, and 90% of child sexual abuse is committed by someone who knows the child. >> and a real big issue with children at this age -- well, children at any age who have been abused is trust. >> reporter: joy riley was sexually abused when she was in elementary school. >> i was experiencing pieces of nightmares and not understanding. >> reporter: she suffered from

debilitating depression and suicidal thoughts. >> you don't think it's depression. you just think that, well, nobody really cares about me because why would they do this to me. >> reporter: riley says a place like safe shores could have helped her deal with her anger and self-destruction and understand that the abuse was not her fault. >> talking about it was the piece that i did not necessarily have, being comfortable enough to talk about it because no one really wanted to talk about it. >> an unresolved trauma, especially one that occurs through abuse, has the possibility of creating anxiety, depression, hyperactivity, inability to sleep. >> reporter: that's why bridgeman says it is critical that abused children receive the therapy they need quickly. >> they have learned that they can no longer have to accept the victimization but that they can actually be thrivers and

most parents by now have already budgeted for their child's new year in school, but have you thought about the costs of getting kids involved after school? retail me not.com did a survey that found parents will intend $400 a year for their child to participate in extracurricular activities. experts say that's why budgeting

for these extracurriculars has never been more important. >> extracurricular rainy day fund, if you will, so they have a bucket to full from should these things pop up throughout the school year. >> one reason parents will spend more is because so many schools across the country are so strapped for funds. this next story is pretty unbelievable, you might want to show it to your kids to remind them of an important lesson, no one likes a showboat. take a look. a french track and field athlete takes off his shirt as he is ahead of the pack during the final stretch of the european championship. he then puts his shirt in his mouth. he held it there and then held it in his hand as he crossed the finish line bare chested and very proud of himself, it seems. he thought he had won his third consecutive gold medal in the race. the problem is you can't do that and he was stripped of his gold medal because the rules state a runner's bib cannot be obscured in any way. well, most of you have

probably never visited a cosmetic surgeon, but looking and feeling better are universal goals. laser technology can help you achieve that goal. dr. steven hopkins joins us to explain. welcome. >> hi, barbara. >> tell us how laserliposuction has changed. there have been some advancements you want to share with us, right? >> laser is the latest technological advancement for liposuction. there's another twist to it now. new studies are showing that we're getting an additional 18% skin tightening with liposuction using the laser, which is huge really. 18% on your money is great, but 18% on your skin is equally good. >> that was always the problem in the past, wasn't it, people would have a lot of loose skin. >> exactly, exactly. and so everybody is not a candidate, but this laser technology has changed the game for a lot of patients. >> so who are the best candidates for this type of surgery? >> the ideal patients have excellent skin elasticity. they're close to their ideal weight, things just diet

exercise can't help with certain areas. arms, love handles, things like that. >> let's have a look at places to consider. >> arms, fabulous places for laser lipo. even breasts can be reduced to a certain extent with the laser. >> and the neck. >> ideal for the neck. especially parents with darker skin. this is a woman actually in back, really tough areas to lose but you can see it's a sculpt. here's another good example of how it can change and take inches away. this is the arms again. >> so a lot of this is not just weight loss, you really feel you've got -- well, if you're going to lose it, it has to come off in a different way. >> no, we always try to encourage people to lose weight first. as i say, the ideal patient is someone close to their ideal weight but still have areas of fat that doesn't respond.
