A father was shot dead as he attempted to kill an eight-year-old girl after killing four members of his family.
Mark Leo Gregory Gago was gunned down by police officers after murdering his parents, girlfriend and their nine-month-old daughter.
Detectives revealed the 42-year-old had a large stash of weapons and swords at the home in Oregon, US, and that he did not shoot his victims.
One neighbour claimed the father had used an axe during the bloodshed but that remains unconfirmed.
The victims have been identified as Olivia Lynn Rose Gago, 9 months; Shaina E. Sweitzer, 31 years old; Jerry William Bremer and Pamela Denise Bremer, 64.
Sgt. Brian Jensen, a spokesman for the Clackamas County Sheriff’s Office said detectives are yet to find a motive for the murders.
He said officers had used lethal force to stop Gago as he attempted to kill a child, said to be his girlfriend’s eight-year-old daughter.
Two people survived the attack and have been taken to a nearby hospital for treatment.
One is believed to be a female roomate who was living at the home, while the other is the eight year old girl.
