DENVER - A man convicted of sexual assaults in two states, and who was also once involved with an underage girl, is missing from a Denver halfway house.
The U.S. Marshals say Matthew Preston Caulk is wanted for violation of federal supervised release. He disappeared from a halfway house in Denver and a warrant was issued for his arrest on Feb. 13.
He was serving eight years of supervised release following a 45 month sentence in federal prison for failing to register as a sex offender in 2010.
Caulk was required to register after a sexual assault conviction in Washington state. In 2007, while unregistered and on the run in Colorado, the marshals say he committed another sexual assault in Lakewood.
Caulk was found after being featured on America's Most Wanted and local media. He had been with an underage runaway.
"We want the public to be aware and help us capture this violent predator before he strikes again," said U.S. Marshal John Kammerzell.
Anyone with information is asked to call the U.S. Marshals Service at 1-877-WANTED2 or Metro Denver Crime Stoppers at 720-913-STOP. A reward of up to $2,500 is offered for information leading directly to an arrest.
