>> she's my baby. >> the search continues for 32-year-old michigan mother of two, venus stewart, after a stunning disappearance. >> i know she would never leave on her own. there's no way she would ever leave on her own. >> i was surprised she didn't wake me up to tell me to watch the kids before she went out to put the mail in the mailbox. i wish she would of. >> cops say venus walked outside the family home early monday morning wearing slippers and pajamas to put a letter in her mailbox, then vanishes. >> i've never seen anyone disappear like this so thoroughly. >> signs of a strig l around the driveway. venus' parents noticed remnants of what appeared to be a scuffle in the gravel in the yard. >> there's absolutely no trace, no hint, no nothing. >> cops calling venus' estranged husband, douglas stewart, their only person of interest because of an alleged rocky marriage. police reportedly find stewart in virginia. he denies he has anything to do with his wife's disappearance and says he's a good citizen and a good person. good evening. i'm nancy grace. i want to thank you for being with us. bombshell tonight. a beautiful girl just graduates nursing school, then goes missing from the local barnes & noble bookstore. we learn the very last phone call she makes before she vanishes into thin air was to her former boss, who we now know to be her married boyfriend. in the last hours police execute multiple search warrants on married boyfriend's house and business. >> there's a goal here. >> help us find her. >> to get everybody to know her face. >> help us find phuong. >> this is just really odd. >> authorities investigating the disappearance of 25-year-old phuong le, have executed search warrants. >> a bunch of suits and ties. >> on the home and office of a man police reportedly say was romantically linked to the missing woman. >> these guys were too quiet. >> they are not telling us what they found. >> cops are keeping a lot of things close to the vest. >> sources say investigators began looking at tuck nguyen, former boss -- >> cell phone records. >> who did they call? >> his number was the last on the cell phone. >> did she say anything about leaving the area, running away? >> no, not at all. >> police will not confirm what was taken. sources say computers were seized from both locations. >> if somebody was doing something, you know, i think she would have said something. >> phuong's family recorded her former boss as a brother. >> i think something would have come out. >> a mn man her relatives describe as a family friend. >> i'm just hoping -- really hoping -- i'm hoping she's safe right now. >> i want to point out that the married boyfriend is not a suspect. he's not a person of interest. according to everything i know right now, he has been cooperating with police. straight out to henry k. lee, reporter with "the san francisco chronicle," author of "presumed dead: a true life murder mystery." henry, everything i'm learning is getting worse and worse. give he me all the updates. >> they have searched mr. tuck nguyen's home and business. he runs postal express in suisun city, same city where phuong le lives, and he's her former boss. of course, she called him on sunday and what we don't know is does he have any involvement in her disappearance? the family says no. >> henry k. lee. a couple of questions, quick yes or no. if you don't know, fine. the police may not have released it yet. number one, do you know how long they spoke on the telephone? >> not sure at all. >> okay. do you know what they talked about other than he says she was angry she had to hand out flyers for her sister's business? anything else? >> that's it. that's what they talked about. >> do you know where he was? has his cell phone been pinged? for all i know he was driving to the front of the barnes & noble to pick her up. where was he at the time of the phone call? >> he says he was home on the day she disappeared. it stands to reason, nancy, the cops would be looking at his cell phone records to jive it up with hers. >> he says he was home. stacey newman, our producer on the story, doesn't he say video surveillance supports his alibi that he was at home? >> yes, nancy. he says he has an alibi. surveillance video from the surrounding neighborhood he lives in he says will prove that he was at home that night and did not leave home. >> wait. so you're telling me he doesn't have a nanny cam or anything like that at his home but believes surveillance video in his neighborhood -- what surveillance video in his neighborhood? >> he says there's videothere that shows people coming and going from the neighborhood. he lives in a very nice somewhat upscale neighborhood in fairfield and says video will prove he did not leave his home the day that le disappeared. >> marc klaas, president own founder of klaaskids foundation. what do you make of this? >> it's incredulous that this gentleman would be able to supply himself with that kind of an alibi. say that he knows that the videotape will prove that. it almost seems like he had something pre-prepared. but you know what, i'll tell you, law enforcement in northern california has plenty of experience in searching for missing persons. so i don't think that there's any region in the country that a person could disappear in where they wouldn't have as much experience to draw from as northern california. >> okay. pat brown, criminal profiler, author of "the profiler: my life hunter serial killers and psychopaths." you're just what we need. you and marc klaas, between the two of you, certainly we can figure this thing out. pat brown, all right, of course, all types of red flags are waves. when you find out not only did she have a married boyfriend who is a former boss, did he fire her? did she quit? why is it a former boss? also, we learned that's the very last person that we know of that she spoke to before she vanishes into thin air. weigh in. >> well, i say two things there. romantic relationship at one point and last person she called. those are absolute connections they have to look at. here's the other thing. that purse in the trunk bugs the heck out of me. i have gone into a bookstore before, put the purse in the trunk. i roll up the windows, lock the car. the only reason her purse would be in the trunk, she left the bookstore and she jumped in the back of the car and sat in the car next to her's or somebody put her purse in the trunk and dumped her car in the barnes & noble lot. only things i can think of. >> thinking this through, pat, first i thought maybe she met somebody in the parking lot and took off with them, but why would she leave everything behind? even if she went into the barnes & noble, why wouldn't she take her cell phone or wallet with her? >> right. if she went in, i agree with that. if she came back out again, if she was going to sit in somebody's car and talk to them, sometimes you open up your trunk and toss it in there to get rid of it while you're sitting and talking. you have your eye on it but don't want it in your lap. that's one thing. or somebody dumped her car there and drove her car to the lot and left it there because they knew she went to barnes & noble and they think that's a place she could get abducted out of. in other words a staged crime scene. >> you know, isn't it true, henry k. lee, with "the san francisco chronicle," joining us in san francisco, didn't she go to the local barnes & noble, the local bookstore, and study? she had just taken her nursing boards, and she was studying for more tests? >> that's correct. barnes & noble, nancy, was a familiar haunt for her, and as the brother has told reporters, it's possible that a complete stranger may have realized what her daily routine was which included the barnes & noble -- >> back it up, back it up. marc klaas, how often is it that someone le's age is an ducted by a complete stranger? >> it it certainly happened to my daughter. that happened to many of of the kids. >> i said le's age. >> i don't know about that. >> 24. >> i would think less often than more. i don't think we want to narrow it down to one individual, at least not at this point. >> marc, you know me better than that. i think everybody's a suspect. i thing i'm a suspect. i have to find out where i was that night. listen, nobody is ruled out. i'm just saying let's look at statistics. let's take an educated look at what happened. what about it, pat? what are the stats? >> well, i mean, there are women who go missing out of parking lots. that's a popular place for serial killers to go and grab their people, but i don't understand why she would put her purse in the trunk if she was leaving the store. what purpose is it going to serve if she's going to get in the car and drive away? that doesn't work for me. i think it's not an abductor out of the lot. >> the family told us today they regard nguyen as a brother and don't believe had anything to do with the disappearance. her friends are simply fighting their fears. >> that we'll never find her or find out what happened to her and she won't come home.

>> she was upset about something about like passing out flyers for her family. >> did she say anything about leaving the area, running away? >> no, knock at all. >> those close to her do not believe phuong took off. >> her disappearance is out of the ordinary and around suspicious circumstances. >> friends remember phuong talking about her old job at the postal store but not nguyen in particular. >> we're like a sisterhood and i think she would have said something. >> and i am getting the information in the last commercial break that police are now denying reports that le was pregnant. saying she absolutely was not pregnant. how do they know? out to you, henry k. lee. how do police know? >> they're not telling us us how they came to that conclusion, but they obviously want to shoo away any rumors. in fact, today nancy, they met with the family of phuong le to clear the air and address any rumors. >> family of who? i couldn't hear you. >> the family of phuong le. the officers did meet with pu huong's family to meet with them, give them an update and clear the air. i think that was a springboard asking about more sense it active issues about any romantic relationship she may have had with this individual or not. >> wait. how do they know whether she's pregnant? >> that's a good question. i don't know how they would define that, but certainly you would find a way to do that conclusively. they said there's a denial that she's pregnant then we have to take that at face value. >> unless they have the ept stick in her hand, henry k. lee, nobody knows anything except her as to whether she's pregnant or not. out to the lines. becky in kentucky. hi, becky. >> reporter: hi, nancy. >> hello, dear, what's your question? >> caller: i wanted to tell you i'm a crime victim myself. my mother was murdered when i was 10, and i very much appreciate what you do to seek justice in this country. >> hey, becky, i bet you still suffer your mom's death even to this day. >> caller: i will never get over it. >> people don't get it unless they've been a crime victim. you go on in life. it's like you break your arm but you learn to flip a pancake anyway. >> caller: uh-huh. >> but it's never the same again. you're never the same again. thank you for sharing that -- >> caller: me and my daughter, chl chloe, and i watch you every night. >> thank you becky and chloe. what's your question, dear? >> caller: i've been thinking about this where she left the windows down. every car i've ever had, you can access the trunk from inside the car. so she wouldn't leave the windows down and put her things in her trunk. >> becky, you're absolutely right. becky in kentucky, becky and chloe watching tonight. just point out something all of us missed, ron shindel, nypd deputy inspector. what about it, ron? she's right. why bother to lock your stuff in the trunk with the windows down? you can reach right in and go, hit the button. >> this is true, but a lot of people put things in the trunk to keep them out of sight. in this case there's so many things that don't make sense. this is just one more thing. >> put him back up. did you say a lot of people put things in the trunk and leave the windows down? >> no, i'm saying a lot of people put things in the trunk to keep them out of sight even if the windows are up or down they don't want the items seen from outside the car. huh, i've never heard of that, to leave your windows down and put your valuables in the trufrg when anybody has to do is reach in and push the button and open the trunk. >> it's true, but all valuables should be out of sight in the car. >> what do you make of the detail? >> that's what i said before. if i'm going into the store and leaving my purse i'm going to roll up the windows and lock it, but if i'm going to sit in a car next to my car i might dump my purse in the trunk because i am watching my car and i know no one's going in my trunk. >> the search intensifies for a 24-year-old california woman last seen as a barnes & noble bookstore. >> the disappearance is out of the ordinary and around suspicious circumstances. >> friends and family members handed out flyers with a picture of 24-year-old phuong le to everyone they could. >> her brother found her car in the parking lot with the windows down and her purse, cell phone and wallet in the trunk. thing as taking a chance?
