A preliminary hearing is underway in Shasta County Court to determine if there's enough evidence to send Mark Duenas to trial for the murder of his wife.
Karen Duenas was found dead in the family's Cottonwood home in May. Her husband of 30 years, Mark Duenas, was arrested in October.
According to the criminal complaint filed by the District Attorney's Office, Mark Duenas was having a phone relationship with a woman out of state and that he told her quote "something bad would have to happen for them to be together".
The complaint also stated that in the initial 911 call, Mark Duenas admitted to the operator that he killed his wife.
In court Tuesday morning the prosecution played the 9-1-1 tape. Several people in the packed courtroom cried as the first and second calls were played, as well as an enhanced version of the first 13 seconds where prosecutors said Mark admitted he killed Karen.
A deputy testified about how neighbors came forward later to report they had heard screams coming from the Duenas' home. The Duenas' five sons were in the courtroom for Tuesday's hearing, along with other family members.
