Two officers were wounded and one killed in two separate shootings early this morning, both of which police suspect involved the ex-LAPD officer who is the target of a massive manhunt.

Police had launched a massive search for Christopher Jordan Dorner, who reportedly wrote an 1,100-word manifesto threatening "unconventional and asymmetrical warfare" against all uniformed Los Angeles police officers after he was fired from the department.

Dorner is also suspected of murdering a high school coach and her fiance in Irvine. Monica Quan was the daughter of retired police captain Randy Quan, who was directly involved in the review proceedings that led to Dorner's removal from the force, according to the L.A. Times.

The first officer-involved shooting occurred in Corona at 1:24 a.m., according to LAPD Officer Rudy Lopez.

Officers were participating in the hunt for Dorner, when they were flagged down by a witness who claimed to have seen him. The two officers soon spotted a blue Nissan Titan matching descriptions of Dorner's vehicle and began to follow. After exiting the freeway, Dorner reportedly stopped, got out of his truck, and fired upon the officers with a "shouldered" weapon, according to Lopez. One officer was grazed by a bullet, the other uninjured.

In Riverside some time later, two officers were stopped at an intersection for a red light when they were reportedly ambushed by a shooter. One officer was killed, another injured, according to Riverside Police Lt. Guy Toussaint.

Toussaint related the details in a press conference captured here by the Press-Enterprise:

Toussaint said there was a "strong likelihood" that Dorner was involved, but said the investigation is continuing.

One reporter asked "Do you consider yourselves under attack?"

"Based on the circumstances of the shooting, yes I do," he said.
