From the Associated Press:

ANAHEIM — Investigators say the suspected killer of two Southern California Gas Co. employees last week blamed the victims for forcing him to resign from the utility’s Anaheim office.
Phong Thuc Tran is believed to be the killer of 37-year-old Hung Duy Dao, whose body was found in his car outside the utility’s Anaheim office, and 43-year-old Charles Santisteban, a supervisor killed in his Pomona driveway the next day.
Tran was found in his SUV with a self-inflicted gunshot wound outside the Anaheim police station.
He died on Saturday at UC Irvine Medical Center in Orange.
Anaheim Sgt. Tim Schmidt says the 36-year-old Tran “had hatred for the victims” because he felt they conspired to force his 2007 resignation.
