Johnny Guevara, 29, was convicted of felony counts of special circumstances murder, carjacking, kidnapping, unlawful taking of a vehicle, street terrorism and being a felon in possession of a firearm.
Guevara faces a maximum sentence of life without the possibility of parole plus an additional 25 years to life in state prison at his March 18 sentencing in Santa Ana.
Guevara was convicted of a carjacking on Oct. 22, 2008. DNA evidence helped convict him of that crime.
Guevara was also convicted of the Nov. 16, 2008, murder of a graffiti "tagging" crew. Guevara drove to an industrial location in Santa Ana in a stolen car and confronted a group of males who were drinking alcohol. Miguel Lopez, 18, was fatally shot in the head after identifying his clique to Guevara.
The next day, Guevara refused to pull over for a traffic stop over not wearing his seat belt. He led police in a high-speed pursuit in his friend's borrowed car and was caught.
DNA evidence left in the stolen car and in the borrowed car led to Guevara's murder conviction.
An accomplice in the first carjacking is still at large.
Anyone with additional information regarding the identity of Guevara's carjacking and kidnapping accomplice is encouraged to contact Supervising District Attorney Investigator Ron Seman at (714) 347-8844.
