Michael Rodriguez Chavez, 22, is expected to be sentenced to 17 years to life in prison at a hearing Oct. 11 at the South Bay Courthouse. The defendant pleaded guilty on the day his preliminary hearing was to go forward.
Chula Vista police said they got a report of a disturbance at 1130 Morgan Hill Drive about 7:15 p.m. last Dec. 1 and made contact with Chavez, who was inside, a short time later. He was detained as he emerged from the home holding the couple’s 3-year-old daughter.
Officers then entered the home and found Yesenia Lynn fatally stabbed, police said. The toddler, who was uninjured, was taken into protective custody and later released to relatives.
Police did not disclose a motive for the slaying but said the couple had been arguing before Chavez stabbed the victim about a dozen times.
The attack happened in the home in which the victim lived with a family member. The defendant was on parole for assault with a deadly weapon in 2011.
Prosecutor Enrique Camarena described the relationship between Chavez and Lynn as “tumultuous.”
