Transcript for Ransom Demands, Strange Emails Raise Questions About Vallejo Kidnapping
is talking about. This is the stuff movies are made of. Horror movies for that terrified young couple. All-new details tonight in the case police thought was a hoax. Tonight, profilers taking us inside his mind. And there's no apology from the police. And tonight, you'll see it all. The most complete play by play in what was said to be a trial run for another abduction down the road. Once again, Cecelia Vega. Reporter: Something scary and strange has happened in the quiet community of mare island in Vallejo, California. An old shipyard building town an hour north of San Francisco. But what exactly did happen? When Aaron Quinn calls police on the afternoon of that terrifying home invasion, he says more than ten hours have already passed since his girlfriend Denise was snatched by an intruder. So why the wait? I think the Vallejo police were quite suspicious from the start. Reporter: Henry lee is a reporter at the "San Francisco chronicle" who covered the case. This ordeal had happened in the predawn hours, yet he didn't come forward until later that afternoon. Reporter: Aaron is taken to the police station and consents to a blood test to determine what drugs he was given. He tells police whoever took Denise left behind their cell phones. Aaron says he's already received a message demanding a ransom, two payments of $8,500. $8,500 is quite a paltry sum, pretty small amount for a kidnap victim. And certainly the police were very suspicious of that amount from the very start. Reporter: Of course, when any woman vanishes, cops want to take a good look at the man in her life, but nothing in Aaron's or Denise's background screams trouble. He was just a very great kid. If there was a conflict, he'd be the person to kind of straighten it out. Never really saw him lose his temper. She has a lot of friends and everybody adores her. She's very well-liked. I don't know of anyone who does not like her. Reporter: But there are no other witnesses to the abduction and no obvious evidence of a break-in. And all that high-tech gadgetry? Former FBI profiler and ABC news consultant brad Garrett says real ransom kidnappings just don't look like this. When you listen to the front end of this case, and from my vantage point some very bizarre details. The tape over the goggles. I mean, it almost sounds like somebody had a movie script and they were Reading it. It was unbelievable. Aaron spent 17 hours with the police without an attorney and we started getting very worried about what was happening. Reporter: Things are getting testy, when Aaron agrees to submit to a polygraph administered with the help of the FBI. The police and the FBI were doing a very hard interview, as we call it. But unfortunately, he didn't like it and he decided to cut the interview off. He submitted to everything. He volunteered DNA samples. He did everything. They should've started thinking, and saying, "Okay, let's look -- let's forget about classifying this guy as a dirtbag. Let's start looking at him as a human being." Reporter: But to police, Aaron is looking less like a victim and more like a menacing mastermind. It was made very clear to us that he was the prime suspect but I didn't think he would be the only suspect. Reporter: And the next day they turn to the public for help. As of this moment Ms. Huskins' whereabouts are unknown and we are treating this matter as a kidnap for ransom. And anyone who has any information about her whereabouts are encouraged to contact the Vallejo police department immediately. Denise Huskins vanished from her boyfriend's home and has been kidnapped and is possibly being held for ransom. Who takes people for ransom these days? It just gives me the chills just thinking about it. It's just bizarre. It's kind of a scary thing. I've got a family, I've got young kids, I've got a wife. So it is kind of scary. Reporter: With the community on edge Vallejo police launch a massive search for the missing blonde 29-year-old. Tonight, Denise Huskins is still missing and police have no suspects. It's like a bad dream and I can't wake up, you know? Reporter: Denise's distraught father, who lives 400 miles south in Huntington Beach, California, sends a message to his daughter. Be strong like you always are 'cause you got -- the family's -- sorry. It's just unreal. It doesn't make any sense. Why would a guy sneak into the place in the middle of the night and take her? I just don't understand. Reporter: Police were saying the same thing, too. Something about the case wasn't adding up. Investigators bring Aaron back in for more grilling. They've questioned her boyfriend, they're continuing to question her boyfriend. Reporter: But this time, he brought his lawyer Daniel Russo along. At a certain point, I would look at Aaron and just go, how is this guy functioning? We don't have all of the facts in yet and that's what he's helping us do, to piece the puzzle together. Reporter: And another piece of this baffling puzzle was about to surface. The day after Denise goes missing, reporter Henry lee goes from covering the case to being cast as a main character in it when a mysterious e-mail shows up in his inbox. I'm standing outside the Vallejo house in the neighborhood where Aaron Quinn lives and in my e-mail I get an audio file as well as a message. The audio file has the voice of a woman. My name is Denise Huskins. I'm kidnapped, otherwise fine. Reporter: It's a proof of life recording and to confirm it's really her, Denise reveals personal details that only she would know. She shared details like the first concert she went to, she says, was a blink-182 concert. Reporter: And to prove she's actually alive and well it references a story in the news that day, the tragic plane crash in France. Earlier today there was a plane crash in the alps and 150 people died. You can hear what is her voice and she says, I'm okay, but it's to give them the impression that yes, this is really happening, and she's in trouble. Reporter: But instead of offering proof that Denise is still alive, it only raises more questions about her abduction. She gave a proof of life audio file that the kidnappers e-mailed to police in which she doesn't sound distressed at all. Reporter: That evening, another clue. While the cops had Aaron's phone, he received two calls from an unknown number. Police later able to track that number to a disposable phone purchased at target with the calls coming from somewhere in lake tahoe. But who was making these calls?
