The bail of a man who allegedly told deputies that he stabbed his wife was set to $5 million in court on Friday.
Marvin Duncan, 59, pleaded not guilty to murder charges.
Deputies said Duncan walked into the Imperial Beach Sheriff's Substation Wednesday afternoon saying he had killed his wife. The body of a woman who had been critically stabbed was discovered in the parking lot of the station and the stabbing victim was found on the ground, just outside a white truck.
When deputies asked the man if he had a weapon, he pulled a knife out from his waistband and set it down in front of officials. Duncan was arrested on the spot.
The victim was revealed to be 36-year-old Rocio Duncan (shown below) a teacher at Mar Vista High School in Chula Vista.
Prosecutors said Rocio was stabbed 15 times in the arm, chest and back of the head. One of the two knives was embedded 3 inches into her body.
He told an acquaintance he was going to kill her over child custody, according to prosecutors.
Duncan was holding two toddlers when he arrived to the substation and allegedly surrendered the other knife when he admitted his act to deputies.
Deputies say the kids are now in the custody of Child Protective Services. Their names and ages were not released.
"I don't have information as to their actual marital status,” Sheriff’s Lt. Glenn Giannantonio told reporters at a briefing Wednesday evening. “(Duncan) did say 'his wife'. But I'm not sure if they were still married or separated or what-have-you."
Deputies say the family is not from Imperial Beach, but they are San Diego residents.
Duncan’s next court appearance is Feb. 25 for a preliminary hearing at South County Superior Court. If convicted he could face 26 years to life in prison.
