WEST COVINA – A jury on Friday convicted a Hollywood man of beating his 62-year-old father to death with a dumbbell in an Irwindale storage facility.

Jonathan Martinez Pedraza, 26, was found guilty of first-degree murder, felony vandalism and two misdemeanor counts of hit-and-run driving, according to Deputy District Attorney Stacy Okun-Wiese.

The jury also found true an allegation that he personally used a deadly and dangerous weapon, the dumbbell.

Pedraza faces a maximum sentence of 27 years to life in prison at his Feb. 10 sentencing in West Covina Superior Court.

Miguel Pedraza of Glendora was killed Sept. 3, 2010 and his body was discovered inside a storage locker at A-1 Mini Storage, 4391 Irwindale Avenue.

The younger Pedraza delivered at least five powerful blows to his father’s head fracturing the skull and causing 10 lacerations, according to authorities.

He then rammed his car though a security gate at the facility to escape before becoming involved in another collision in Baldwin Park.

He crashed into two other cars at a parking lot in the 14500 block of Ramona Boulevard and fled. Baldwin Park police found him hiding on the roof of a apartment complex in the 14400 block of Pacific Avenue and arrested him.

A judge in October 2011 ruled that Jonathan Pedraza was mentally competent to stand trial.
