Denver police announced Saturday they have identified a suspect in the abduction and sexual assault of an 8-year-old girl.Police obtained an arrest warrant for Bret Lee Luckett Thompson, 27, also known as Wyatt Thompson.He is wanted for investigations of 2nd degree kidnapping, a class 2 felony and for sex assault on child, a class 3 felony."Obviously we're at an important stage. We have a suspect. We need to get this individual in custody and move forward. This type of nightmare should not happen," said Mitch Morrissey, Denver District Attorney.Police said Thompson was last seen driving a 1999 white Pontiac Montana minivan. The minivan may have Colorado license plate 697WJA or Louisiana license STV813.The Denver office of the FBI has joined in the hunt for Thompson. Police said Thompson should be considered dangerous.He is described as 6 feet tall, weighing 190 pounds, with short, brown hair and green or hazel eyes.Thompson has distinctive tattoos, including an "S" and "S" on top of one another on the inner section of his right forearm."He does have an arrest record from other states. And I don't want to go into details about that because we're searching far and wide," said Division Chief Dave Fisher. "He's familiar with horses. He has experience in trimming horse's hooves. And we know that here in the metropolitan area he spent some time in a rural area where he did work with horses in that fashion."Fisher said Saturday that a search warrant was also executed Friday night."We've been working through the night on this. There've been a lot of things going on. It's moving fast," Fisher said.7NEWS checked and found what appear to be addresses for Luckett-Thompson in Clearwater and St. Petersburg, Fla.Anyone with information on Thompson's whereabouts is asked to call Crime Stoppers at 720-913-STOP (7867).Thompson is suspected of grabbing an 8-year-old girl on Thursday in an alley at S. Raleigh Street and West Virginia Avenue and forcing her into his van. The girl was dropped off on Federal Boulevard near Mile High Stadium about 90 minutes later. Police said she had been sexually assaulted.A volunteer with the Denver Rescue Mission told 7NEWS he recognized Luckett-Thompson and believed he had seen the suspect at the shelter Thursday night.A Denver police spokesman said investigators were following up on that lead now.A retired Denver police detective told 7NEWS he spent one hour with the 8-year-old victim to produce the sketch that greatly helped police.But investigators said the child herself was "the hero"."I have seen many if not most adult victims that did not handle themselves as well as she did at eight years of age," Fisher said. "Her ability to recall at such a young age, considering the horrific experience and victimization that she endured I just think, again, in 26 years of being a police officer, I think she's probably the most amazing victim I've ever encountered."In fact, Fisher said, the sketch was so good that several calls came into Crimestoppers from viewers that saw the sketch and recognized it as Luckett-Thompson.With the release of Luckett-Thompson's name and photo, law enforcement hoped he would be caught soon."He can run but he can't hide. We will find him. And he will be brought to justice in Denver," Fisher said.
