A 52-year-old Tustin man pleaded guilty Friday and was immediately sentenced to 40 years to life in prison for gunning down his estranged wife in Anaheim’s Peralta Canyon Park three years ago.

Humberto Servin of Anaheim pleaded guilty to second-degree murder with a sentencing enhancement for discharge of a gun causing death.

Servin fatally shot 42-year-old Claudia Espino Garcia of Tustin May 12, 2016, in the park at 115 N. Pinney Drive.

Anaheim police Sgt. Daron Wyatt said officers responding to a report of gunfire at the park found the victim slumped over in the driver’s seat of her vehicle.

Witnesses, including several children, gave officers a description of Servin and his vehicle, Wyatt said.

About 15 minutes later, officers located Servin’s 2002 gray Dodge Ram truck in the parking lot of the Anaheim Police Department’s East District substation at 8201 E. Santa Ana Canyon Road.

Servin, who drove to the substation to surrender, was taken into custody nearby, according to the Orange County District Attorney’s Office.

The victim and Servin had not lived together since 2008, according to prosecutors, who said he arranged to meet in the park with Garcia.

Servin opened the passenger side door and shot the victim, but he left the area when the couple’s daughter ran toward the vehicle, according to prosecutors.

There were no reports of domestic disturbances when the couple lived in Anaheim, Wyatt said.

On May 22, 2012, Garcia was ordered to pay $283 a month in child support for the couple’s two sons, who were 17 and 14 years old at the time of the killing, according to Orange County Superior Court records. Authorities have not released the age of their third child, a daughter.
