MARTINEZ -- Jury deliberations begin Monday at the murder trial of a Fairfield man who admits to fatally shooting his best friend in Pinole in 2011.

Brian Fitch, 43, testified he shot 42-year-old Jeff McCoy in self-defense after McCoy, a San Pablo resident, threatened him with a gun. Fitch's attorney asked the jury to find his client not guilty; if the jury abides, it would be the second time Fitch is acquitted of murder charges in Contra Costa County Superior Court.

Fitch testified in 1993 that he fatally shot Anthony Earl Davis in self-defense and was found not guilty. Davis, like McCoy, attended Pinole Valley High School with the defendant.

The prosecution argued that Fitch should be convicted of first-degree murder for killing McCoy. He shot McCoy 10 times, mostly in the back, in a premeditated attack motivated by a paranoia that McCoy and other friends were having sex with his wife, the prosecutor said.

Attorneys gave their closing arguments Thursday after three weeks of witness testimony.
