The Clackamas County Sheriff’s Office is investigating a double homicide following a shooting in unincorporated Clackamas County. Photos and video are attached.

At about 11:13 p.m. on Saturday, March 20, 2021, Deputies from the Clackamas County Sheriff’s Office were dispatched to the report of a shooting at the Reflections apartment complex, located at 8800 SE Causey Loop in unincorporated Clackamas County, near Happy Valley. 

Deputies received additional information while responding that two people had been shot inside an apartment.  The suspect was seen fleeing the location on foot.   

Deputies arrived within minutes to check for the suspect and render aid to the victims.  Both of the victims were deceased when deputies arrived.

K9 Ronnie from the Oregon City Police Department responded to assist deputies with a search for the suspect.  Deputies searched the area but the suspect was not immediately located.

Multiple personnel responded to the scene to investigate including detectives, crime scene investigators, Clackamas County District Attorney’s Office investigator and deputy district attorney, and a Clackamas County deputy medical examiner.

The suspect was identified as Amanda Kate Gregson, 39. 

A few hours later, on Sunday, March 21, at 1:47 a.m., deputies responded to a welfare check at the Monarch Hotel located at 12566 SE 93rd Ave in Clackamas.  Deputies discovered the subject they were checking on was Gregson.

Deputies detained Gregson without incident.  She was transported to the Clackamas County Sheriff’s Office for an interview with detectives. Deputies and K9 Ronnie checked inside and around hotel for possible evidence.

Following the detective interview, Gregson will be transported to the Clackamas County Jail and booked on a count of Murder in the First Degree.

The two victims are both adult males.  Their identities are not being released at this time as family notifications are pending.
