CHICO, Calif. – Thanks to a DNA match, an arrest has been made in connection with a 2003 case in which a woman was held at knife point and sexually assaulted in Chico.

On Thursday morning, detectives with the Chico Police Department located 58-year-old Glenn Leland Simpson in Paradise and arrested him for multiple sexual assault-related charges, according to Lt. Mike O'Brien.

O'Brien said that on Aug. 11, 2003, a 25-year-old woman was held at knife point and sexually assaulted in her Normal Avenue home by a then-unknown assailant.

Evidence from the scene was submitted to the California Department of Justice's Bureau of Forensic Services, and eventually searched against the Combined DNA Index System database, O'Brien said. However, at that time, the results were negative.

The case was vigorously investigated by lead Det. Matt Madden, but remained unsolved for nearly eight years, O'Brien said.

O'Brien explained that the Chico Police Department recently received information from the California Department of Justice's Bureau of Forensic Services regarding a National DNA Index System match involving the case.

The DNA match involved the case evidence and Simpson, who O'Brien said had been ordered to provide a DNA sample pursuant to a marijuana-related conviction in the state of Utah.

Chico Police Detectives determined that Simpson resided in the town of Paradise and, after consultation with the Butte County District Attorney's Office, an arrest and search warrant was obtained for Simpson regarding this sexual assault, O'Brien said.

Simpson is being held in the Butte County Jail with bail set at $400,000, O'Brien said.
