Update 7:07 p.m., May 1: Police have identified the suspect as Jeb Colin Brock, 42.

Officers shot and killed a man who is reported to have stabbed four adults early Monday in Southeast Portland.

Officers responded to the 13100 block of Southeast Center Street about 4:15 a.m. and found the man holding one of his victims, a woman, at knifepoint, according to Portland police. Officers removed a baby from the room and then addressed the suspect, police said.

They deployed less-than-lethal and lethal rounds at some point in the encounter, according to police. Neither the three involved officers nor the baby were hurt.

Police said three men and the woman were taken to hospitals with “substantial injuries.” Police didn’t know the victims’ conditions later Monday morning.

Police said the victims knew the suspect but didn’t elaborate on their relationships. No one involved has been publicly identified.

“Based upon preliminary information, it appears our officers acted quickly and heroically to save lives,” Chief Danielle Outlaw said in a statement. “We will learn more details as the investigation unfolds and appreciate the community’s patience as we gather the details of what transpired.”

Jim Young, who lives in the area, told The Oregonian/OregonLive he was awoken early Monday to the sound of police arriving on his block, which is in the Powellhurst-Gilbert neighborhood. He didn’t hear any gunshots.

“I heard a lot of police action,” he said. “All I saw was police blocking the street and in front of houses.”

Kathy Laing, who has lived in the area for 47 years, said she didn’t see or hear any commotion early Monday. But flashing blue lights in her window woke her up about 4:30 a.m.

“There was just flashing lights. No sirens or anything,” she said.

Late Monday police identified the three officers involved. They are: Sgt. James Mooney, a 10-year veteran of the force, and Officer Michael Gonzalez, a 2-year veteran. Each used lethal force. In addition, police said 2-year veteran Aaron Rizzo used less lethal force.

The three involved officers were put on paid administrative leave, which is standard procedure after police shootings.

The incident was the second fatal Portland Police Bureau shooting this year.

A Portland police officer fatally shot 36-year-old Andre Gladen, a legally blind man, in a stranger’s home in early January. A grand jury found in February that the officer who shot him was innocent of criminal wrongdoing. The officer was not indicted.

A Portland officer also fired his weapon after responding to a reported domestic disturbance early that month. No one was hurt in that case.

Police urge anyone who has information about Monday’s investigation to contact Detective Vince Cui (503-823-0449; vince.cui@portlandoregon.gov) or Detective Travis Law (503-823-0395; travis.law@portlandoregon.gov.)
