Police: Fire that killed 4 was arson

OKLAHOMA CITY, Nov. 10 (UPI) -- A house fire that killed three women and a man in Oklahoma City was deliberately set, investigators said Tuesday.

Firefighters found the bodies Monday morning, police said. The identities of the victims had not been released a day later, but police said the man was not Jose Fernando Fierro, 31, who rented the house and whose truck was parked outside, The Oklahoman reported.

Investigators said they were looking for a man believed to be in the house at around the time of the fire but would not say if he was Fierro. They said he was not a suspect but could provide information.

The landlord said Fierro had been living in the house for three months.
