Temecula Man Found Guilty of Murder

A man accused of fatally shooting a 20-year-old Temecula woman through her bedroom window was found guilty on all charges today.

Jose Adan Martinez, 20, was convicted of premeditated murder with enhancements of using and firing a gun and carrying a loaded gun as part of gang activity, according to court records.

The jury came to a verdict after only four hours of deliberation. Sentencing is scheduled for May 25 at the in French Valley.

The man drove with several friends to the home of Maria Semental, the victim, on June 16, 2010, slipped into her side gate, shot six rounds through her window, ran away with a smirk on his face, and sped away,

The defense argued that nobody saw Martinez pull the trigger except one person, and he may have been the real gunman,

The murder sprung from a fissure in Martinez's and Semental's gang. An older member living in Mexico assumed leadership of the group, and some of the younger members -- including Semental -- refused to follow the new leader's orders.

Semental called the leader and got in a heated argument with him. A few days later, she was killed.

The killing was likely ordered by the new leader, though no evidence was presented in the trial,
