Anaheim police rushed to an apartment near the Santa Ana Freeway on Sunday on a call about an in-progress assault, but they were too late to save the lives of the couple they found there.

Andres Alvaro-Robles, 67, was pronounced dead at the scene, Anaheim police said, and 65-year-old Teresa Lopez-Miguel was rushed to a nearby hospital, where she was pronounced dead.

Both suffered “major injuries,” police said, but did not describe the injuries.

The couple’s son, 43-year-old Carlos Manuel Robles-Lopez, was found at the apartment and taken into custody without incident.

He’s been charged with first-degree murder in the death of his parents and is behind held on a $1 million bond.

Detectives are still investigating the crime and have asked that anyone who has had recent contact with the suspect to contact Orange County Crime Stoppers at 855-TIP-OCCS.
