CLACKAMAS COUNTY, OR (KPTV) – The Clackamas County Sheriff’s Office says deputies shot and killed a man who they say killed four people.

Deputies responded to a domestic violence call from a house on South Barlow Road near Highway 211 around 10:15 Saturday night. 

They say when they arrived, they found one person dead outside the home and heard screams coming from inside. 

There, they say they found the suspect – 42-year-old Mark Leo Gregory Gago of Woodburn – trying to kill a young girl. 

Deputies used deadly force on Gago, saving the girl's life. Deputies then found three other people dead inside the home.

Deputies say the four homicide victims ranged in age from an infant to someone in their mid-60s. 

They were identified as 9-month-old Olivia Lynn Rose Gago, 31-year-old Shaina E. Sweitzer, 66-year-old Jerry William Bremer and 64-year-old Pamela Denise Bremer. All were Woodburn residents. 

A neighbor told FOX 12 a woman inside that house came rushing over for help Saturday night, saying Gago had attacked her with some sort of ax or splitting maul type thing while she was sleeping.

She told the neighbor Gago may have been high on meth.

“She came running down here wearing nothing but pajama pants and a t-shirt. No shoes, no coat so clearly she was in a hurry to get out of the house,” the neighbor said. “She wrestled with him, got the weapon away from him and escaped the house.”

The girl and the woman who also survived were taken to an area hospital with non-life-threatening injuries.

Investigators believe the victims, survivors and suspect had all lived in the house together and were possibly related. 

No deputies were injured during the incident. Five deputies and a sergeant have been put on paid administrative leave in line with department policy. 

South Barlow Road was closed between Highway 211 and South Schneider Road for several hours during the investigation.

Anyone with information on Gago or the events that led up to this is asked to contact the Clackamas County Sheriff’s Office Tip Line at 503-723-4949 or by using the online email form and reference case #19-001568.
