Officials say they arrested the teen on Friday in the 5200 block of Clayton Road in Concord. He was booked into Santa Clara County Juvenile Hall without incident.
Park-Petttiford was killed in the parking lot of a 7-11 during an attempted carjacking on November 16. Police say the two suspects then went on a crime spree, robbing three other locations and leading police on a high-speed chase that ended in an officer-involved shooting.
A 10-year veteran of the department was injured in the shooting. He was treated for his injuries at a local hospital and released.
The first suspect, 26-year-old Jonathan Wilbanks of San Jose, was the night of the crime spree. He appeared in court Wednesday but did not enter any plea to any of the eight felony counts against him. He's scheduled to do that on December 25.
