A day after a man suspected to be renegade ex-cop Christopher Dorner died in a blazing mountain cabin, police from around the Los Angeles area and beyond gathered to bury an officer who authorities say Dorner killed.

A squad of bagpipers led Michael Crain's flag-draped casket through a cordon of blue uniforms into a church Wednesday in Riverside, the Los Angeles suburb where he served 11 years on the force.

Investigators say Crain was one of four people shot and killed by Dorner, a fired Los Angeles cop who launched a vendetta against his old department last week.
