Former LAPD Officer Christopher Dorner — accused in the killings of four people — stalked at least five people connected to the Los Angeles Police Department in the weeks before his alleged murder rampage, according to law enforcement sources.
Officials say the stalking incidents indicate that Dorner planned his campaign at least a month before his alleged killing spree in early February.
On a day in early January, a man walked up to the front door of a South Bay home and knocked. The homeowner, an LAPD captain, looked outside. Although the two had met before, the captain didn't recognize the large black man standing in his walkway and waited behind the closed door until he left. Weeks passed, and the 23-year veteran of the LAPD thought nothing more of the encounter.
About a month later, after Dorner began his alleged killing spree, the captain realized the man at the door had been Dorner, sources said.
Police allege that by then, Dorner had begun a rampage of revenge against law enforcement officials whom he blamed for his 2009 firing from the force. Police say that he killed the daughter of a retired LAPD official and her fiance, and then two officers, before apparently taking his own life during a standoff with police at a Big Bear cabin on Feb. 12.
