Tualatin Valley Fire & Rescue crews responded to a house fire around 1 a.m. in Cedar Mill.
The house is located in the 12800 block of NW Lovejoy Ct.
Multiple callers to 911 reported seeing heavy flames and dark smoke coming from the residence.
Crews from TVF&R station 61 arrived within minutes of being dispatched and found heavy flames coming from the front of the residence with a partial roof collapse near the front door.
Firefighters initiated an aggressive fire attack and began to search for victims inside the residence. During the search firefighters located three fire victims inside the home. The victims were removed and brought to awaiting medical personnel where lifesaving efforts were immediately started.
Due to the volume of fire and the number of victims located the incident commander called for a second alarm to bring more resources to the scene.
All three victims were transported to a local area hospital with life-threatening injuries.
TVF&R fire investigators are working to determine the cause of this fire. It is unknown at this time if the home contained working smoke alarms.
