A 37-year-old woman was sentenced today to 15 years to life in prison for killing a Los Angeles police officer when her SUV slammed into his motorcycle three years ago, the Los Angeles County District Attorney's Office announced.

Qaneak Shaney Cobb entered a no contest plea to one count of second-degree murder earlier this month.

Deputy District Attorneys Mary Murray and Garrett Dameron of the Crimes Against Peace Officers Section prosecuted the case.

On April 5, 2014, LAPD Officer Christopher Cortijo, 51, was stopped at a red light behind another vehicle at Lankershim Boulevard and Saticoy Street when a Chevrolet Blazer driven by Cobb hit him from behind.

The SUV was traveling about 53 mph at the time of impact, prosecutors said. The officer was killed when he was crushed between two vehicles. Cobb was driving under the influence of cocaine at the time of the crash, prosecutors added.

Case BA435352 was investigated by the Los Angeles Police Department.
