Days after allegedly murdering parents, Martinez man dies from banging his own head into jail wall, sheriff says

"MARTINEZ - Days after he allegedly killed both his parents inside their Concord home, a Martinez man smashed his own head into the wall of his jail cell, then died hours later, after being treated at a hospital, according to police. Kirk Richardson, 61, banged his head into the wall of his cell at the Martinez Detention Facility repeatedly at around 5:45 a.m. Thursday morning."

"Richardson was charged last week with murdering Joyce Richardson, 85, and William Richardson, 90, in a New Year's Eve shooting at the couple's Concord home. Authorities say Kirk Richardson has a history of mental illness and gave an erratic and delusional confession, stating that he'd thought of killing his parents for decades but also referring to himself as "Jesus" and stating he was "proud to be named after Charlie Kirk," who was born about 30 years after Kirk Richardson."

"According to Concord police, Joyce Richardson called 911 on New Year's Eve and reported her son had knocked her and her husband over and was behaving unpredictably. After an officer arrived, he heard three gunshots coming from the home. Authorities say that on Dec. 30 and New Year's Eve, Kirk Richardson made multiple calls to police, first reporting the burglary of a firearm and a crossbow, then calling to clarify that his mother had apparently taken the weapons."
