MURRIETA, Calif. (AP) — A man who randomly killed a woman by hitting her with a liquor bottle as she waited in the checkout line at a Southern California pharmacy has been convicted of murder.

Riverside County jurors deliberated about 90 minutes Monday before finding Brian Saylor guilty. He faces 25 years to life in prison.

Prosecutors say Saylor was in a CVS Pharmacy in Temecula in 2016 when for no reason he struck Tammy Serrano in the side of the head with a bottle of bourbon.

She died without regaining consciousness.

The 54-year-old Serrano had stopped to buy makeup with her daughter, who was visiting on spring break from college in Arizona.

Authorities say after the attack, Saylor walked outside, smoked a cigarette and waited for police to arrest him.
