A man was arrested for allegedly killing his wife and two children in Modesto on Saturday.

Oscar Espinoza, 28, was found bloodied with self inflicted wounds outside a home in the 1600 block of Bay Meadow Drive on Saturday. Modesto police were called to look into an assault at the home just after 7 p.m. When officers arrived, they found the three victims inside the home: 30-year-old Tiffany Espinoza, 9-year-old Spencer Giese and the suspect's 4-year-old son Edward Espinoza.

The official cause of death has not been released by the coroner, but police said the victims’ injuries were consistent with blunt force trauma. Evidence at the scene indicates that the murders either happened late Friday evening or early Saturday morning.

On Wednesday, Espinoza was released from an area hospital and booked into the Stanislaus County Jail for three counts of murder.

The brother-in-law of the deceased mother, Matthew Page, said his family is struggling to cope with their sudden killings.

“Everybody is very confused and everybody is trying to really figure out how to process... what's happened here,” Page said.

Neighbors and family members said there were no signs that could have predicted whatever may have happened.
