SANTA ANA, Calif. — A former college student was sentenced to life without parole on Friday for the murders of his parents while they slept in their upscale California home and the attempted killing of his younger brother.

Ashton Sachs, 22, was sentenced to multiple life terms at a court hearing in Santa Ana, City News Service reported.

Sachs pleaded guilty last month to murder and attempted murder charges.

Authorities say Sachs drove from his college in Seattle to his family’s San Juan Capistrano home in February 2014. They say he shot and killed his parents, Bradford Sachs, 57, and Andra Sachs, 54, and then shot his 8-year-old brother, who was left paralyzed.

Authorities say Sachs also fired at his 17-year-old sister but missed.

Senior Deputy District Attorney Mike Murray said he did not know Sachs’ motive for attacking his family and was glad his siblings did not have to testify at trial.

During the hearing, Lisa McGowan, the sister of Bradford Sachs, addressed the defendant, according to KABC-TV.

“I have been told by my friends and family that in order to move forward I need to forgive you,” she said, wiping away a tear. “Well, here’s my choice. At this time I can’t forgive you for what you did. Maybe someday, but not today.”

Sachs was acting as his own attorney when he entered a guilty plea.
