Police announced that the shooter in a chaotic Orange County shooting spree was 21-year-old Ali Syed, who ultimately shot himself.
A computer suicide note was found indicating the murders of three Orange County residents on Feb. 19 were pre-meditated, according to the Orange County Sheriff's Department.
Ali Syed, 20, allegedly killed three in Orange County before killing himself on Feb. 19. On a computer removed from Syed's bedroom, authorities found a document titled "Suicide Note," according to a press release. The document was created on the day of the murders within an hour of the 911 call from the house where Syed lived with his mother.
"Within the note were indications that the events Ali Syed was responsible for were pre-meditated and planned," the press release says.
The information comes from preliminary computer forensic analysis, according to the OC Sheriff's Department. They also note that while they continue to investigate, Sheriff's Homicide investigators have yet to find a prior connection or relationship between Syed and his victims.
