Oregon City police are asking for the public's help in finding a man reported as missing and possibly endangered.

Sgt. Matthew Paschall, Oregon City Police Department spokesman, said Adrien Arin Chase, 35, was reported missing Dec. 7 by family members who said he suffers from bipolar disorder and apparently has not been taking his medications.

"He may be extremely manic and has a history of disorderly conduct, assault and eluding police," Paschall said. "He even could be suicidal."

Paschall said Chase has been hospitalized in the past for mental health treatment. He said Chase likely took off on late on Dec. 5 – his birthday.

"He may have been especially depressed," Paschall said.

He said Chase reportedly was spotted in the area of Southeast 122nd Avenue and Powell Boulevard in Portland, in the company of local transients. However, police have been unable to verify the sightings.

Chase is described as 5-foot-8, 150 pounds, with brown hair and brown eyes. He has had a full beard in the past, but is thought to be clean-shaven now.

Paschall urged anyone who sees Chase to call 911 or Clackamas County emergency dispatchers at 503-655-8211. Anyone with information about his whereabouts can call the Oregon City Police Department's tip line at 503-496-1616.
