According to a press release from the Cornelius, Washington PD (yes I was too frigging lazy to write it myself last night):
On November 4, 2012 at about 11:01 AM, Officers of the Cornelius Police Department responded to report of a Welfare Check at 452 S. 9th Ave. in Cornelius in response to a report of a small child reporting “someone” was hurting their mother. While reroute, officers were further informed that the line had been disconnected and there were sounds of a possible assault in the background.
Upon arrival, officers made contact with the home owner who advised she had been assaulted and her boyfriend had also poured gasoline on her, himself and around the house. She and her two children had escaped from the house. She and the children (the children were not harmed) were transported to the hospital.
The suspect in this case, Amaury Lopez, DOB/12-21-76, barricaded himself in the house. Due to the fire and explosive danger from the gasoline, surrounding houses were evacuated. Officers from the Cornelius, Hillsboro, and Forest Grove Police Departments as well as Deputies from the Washington County Sheriff’s Office responded to the scene. The Washington County Interagency Hostage Negotiation Team responded and conducted the negotiations with Lopez who finally surrendered to police at around 4:00 PM.
Lopez was taken into custody and transported to the hospital. Upon release from the hospital, He will be lodged in the Washington County Jail on charges of Attempted Murder, multiple Assault charges, Kidnapping and additional Domestic Violence charges.
Once the house was deemed safe for entry, due to the gasoline danger, police executed a search warrant for evidence. The investigation is on-going.
