Toxicology reports show Zoloft and Xanax were found in the blood of the man who killed three people and himself in OrangeCounty.

Cops say 20-year-old Ali Syed went on a shooting spree in Orange County in February, killing three people before shooting himself in the head.

The Orange County Sheriff's Department says it's not clear if the meds were prescribed to Syed.

Zoloft and Xanax are used to treat symptoms like depression and anxiety. 

A suicide note was found on Syed's computer, but detectives wouldn't say if it included a motive.
