TULSA - Update
The victims have been identified at 34-year old Charlie Dake, 35-year old Melissa Dake, 54-year old Glenda Harper and 46-year old Tammy Brunson.
Police say a lone gunman opened up inside a north Tulsa home Saturday evening, killing two people and sending three more to the hospital.
Tulsa police Capt. Dave Roberts told KRMG at the scene the emergency call came in at about 7:15 p.m.
Police arrived in the 1300 block of N. New Haven, just south of Pine St., but initially didn't see anything.
They found a back door open, and then soon heard someone calling for help.
Capt. Roberts said the victims were three women and two men, all adults.
One woman and one man died at the scene; a second woman died at an area hospital.
The only description of the shooter was a white man, possibly in his 40s.
All five people were in the same room when they were shot, a garage that had been converted into some kind of rec room or sitting room.
Capt. Roberts could not say whether police found any weapons inside the home, or any signs of illegal activity.
He did say other people were inside the house in other rooms, and as far as he knew they all stayed until police arrived and were cooperating.
Witnesses heard a vehicle drive off at high speed, but didn't get a look at it, he added.
There have been 62 homicides in Tulsa in 2013.
