The Portland Police Bureau released body camera footage from a June in-custody death of a man during a welfare check in North Portland.

PPB uploaded the video, over an hour in length, to its YouTube page on Friday. The video is listed as “age restricted content” and viewer discretion is advised.

Officers responded to an apartment complex in the 8500 block of North Argyle Way in the Kenton neighborhood just after 10 p.m. on June 27 to perform a welfare check on an adult male, later identified as 52-year-old Damon Lamarr Johnson.

According to police, Johnson had flooded his apartment, spread shaving cream on his walls and hung knives from his window, resulting in the evacuation of the complex’s floor. Three officers responded to scene, requesting that paramedics be staged nearby to assist.

After making contact through an open door, the officers’ body camera footage shows the three attempt to take Johnson into custody on a “mental health-related police officer hold.” The footage shows one officer tell Johnson to “not resit or force will be used against (him)” before the three pull him away from a window.

Officers managed to hand-cuff Johnson laying face-down after approximately four minutes of struggle. The video shows officers repeatedly telling Johnson to “stop resisting” while calling for medical support to sedate him.

Officers are also heard on the video saying that they are trying to help Johnson, patting his back after cuffing him.

At 10:34 p.m., the footage shows one officer say that paramedics are “on their way up” to the scene. While waiting for paramedics to arrive, Johnson becomes unresponsive. At 10:35 p.m., one officer is heard asking if Johnson is breathing before repeatedly attempting to wake him up.

Paramedics arrive at the scene at 10:37 p.m., and began to perform CPR on Johnson for over 15 minutes, according to police.

At just after 11 p.m., Johnson was transported by paramedics from his apartment to a nearby hospital, where he was later pronounced dead.

Homicide detectives were called to the scene following the incident in accordance with bureau policy regarding in-custody deaths, a PPB spokesperson wrote in the initial press release. PPB Chief Bob Day, Multnomah County District Attorney’s Office and the Medical Examiner’s Office also responded to the scene, per the release.

The official cause and nature of Johnson’s death is still under investigation, according to PPB.

KOIN 6 News spoke with Johnson’s sister, Teri, on Friday. She said, “The pattern that this police department has with these types of incidents involving people with mental illness is disturbing and it needs to be rectified, because people’s family members are priceless.”

“Training to deal with people in the throws of manic episodes is needed as well as CPR because they did not look prepared,” she told KOIN 6 News.

The three officers — later identified as Officers J.P. Duque Valencia, Jason Epton and Travis Wortman — were placed on administrative leave.

No further information is available at this time.
