Tyrone McAllister, 18, and a 16-year-old boy could face charges including attempted robbery, elder abuse and assault following Monday's attack in the city of Manteca. Police say they are investigating the attack
as a robbery, not a hate crime, The Modesto Bee newspaper reported.
McAllister is the son of Union City Police Chief Darryl McAllister, who wrote Wednesday on Facebook that "words can barely describe how embarrassed, dejected, and hurt my wife, daughters, and I feel right now."
The chief said his son began running away and getting into trouble about two years ago, committed several theft-related crimes and spent several months in juvenile detention. Later, as an adult, the younger McAllister spent another three months in jail, his father said.
"Violence and hatred is not what we have taught our children; intolerance for others is not even in our vocabulary, let alone our values," he wrote. "Crime has never been an element of our household, our values, nor the character to which we hold ourselves."
