Arvada Man Charged With Sex Crime Involving Alaska Teen


An Arvada resident and former teacher at an area music school has been charged with traveling from Colorado to Alaska to engage in illicit sexual conduct with a child.

According to a federal indictment, Brock Jon Purviance, age 30, of Arvada, Colorado traveled from Colorado to Alaska in August of 2004 to have sex with a girl who was 15-years-old at the time. Purviance allegedly met the child in an online chat room and corresponded with her via the computer and telephone before traveling to Alaska.

Purviance is in custody in Alaska pending his trial which is scheduled to begin on September 6, 2006.

Arvada police detectives are investigating to determine if Purviance may have had sexual contact with any children in Colorado. He was a guitar teacher at the Denver School of Music, located at 5275 Marshall Street in Arvada. The Denver School of Music has cooperated fully with investigators.

If you have any information that may be helpful in this investigation, please call 720-898-6900 to report information.

Purviance was indicted by a federal grand jury in Anchorage, Alaska on April 19, 2006.  He was arrested in Arvada on May 22, 2006.  The current criminal charge against Purviance carries a maximum sentence of 30 years.

The case was investigated by FBI agents in Alaska, along with U.S. Immigration and Customs Enforcement agents in Alaska and Colorado, with assistance from the United States Postal Inspection Service and the Arvada Police Department in Colorado.

The charge against Purviance is merely an accusation, and the defendant is presumed innocent unless and until he is proven guilty.

Questions about the federal prosecution of Purviance should be directed to Jeff Dorschner, press officer for the U.S. Attorney's Office, at 303-454-0243.  Questions about the investigation into additional victims should be directed to Susan Medina, spokeswoman for the Arvada Police Department, at 720-898-6654.
