Convicted killer's son arrested for child molestation


CHICO, Calif. - The man arrested in Chico for allegedly sexually assaulting a 10-year-old boy is the son of convicted wife killer Mark Duenas.

Jacob Mark Duenas, 33, was taken into custody Thursday after a nearly 4-month investigation.

According to the Chico Police Department, on December 30, 2014 an officer interviewed the victim after the child reported he was sexually assaulted in 2014.

The child identified the suspect as Duenas, a former California Highway Patrol officer in Salinas, Calif.

The juvenile reported that the incidents took place within the city of Chico on numerous occasions. After obtaining a credible disclosure of sexual abuse, the case was sent to the Chico Police Department Detective Bureau for continued investigation.

Detectives coordinated with the Butte County District Attorney's Office, and the Butte County Child Services Division (CSD). A forensic interview was completed, and the child statement was confirmed to be credible. Detectives also developed other evidence that further strengthened the case.

On Thursday, detectives obtained a warrant for Duenas' arrest. Detectives found Duenas in north Chico, where he was arrested without incident.

Duenas was booked for continuous sexual abuse of a minor. Bail was denied. After booking, Duenas was sent to the Butte County Jail.

According to the Monterey Herald, Duenas was also convicted of child molestation in 2008.

Jacob Duenas is the second-eldest son of Mark and Karen Duenas. Mark Duenas was sentenced to 25-years-to-life in prison on December 6, 2013 for the May 2012 murder of his wife Karen.
