Officials: Dorner Stalked Five People Before Rampage

May have planned campaign for at least a month

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.
