SAN BERNARDINO - Thousands of law enforcement officers from across the Southwest gathered to honor to San Bernardino County sheriff's Detective Jeremiah MacKay, who was killed in the violent conclusion of the manhunt for fugitive former police officer Christopher Dorner.

Officers stood at attention and saluted as MacKay's coffin, draped with an American flag, was escorted through the San Manuel Amphitheater on Thursday by deputies from MacKay's Yucaipa station. MacKay's family and friends followed, joined by four sheep dogs and a rider-less horse.

The 35-year-old MacKay was a husband and father of two. He had been with the Sheriff's Department for 15 years.  Authorities say he became the fourth and final person Dorner killed.

San Bernardino County Sheriff John McMahon said MacKay "stood for good against evil."
