The station reports that according to Fresno Police Chief Jim Dyer, the gunman has been identified as 42-year-old Laurence Jones, who had been an employee at the poultry processing plant for 14 months.

According to KGPE, Jones showed up to work about 5:00 a.m. and, as one coworker put it, did not appear to be himself.
