Police are looking for a man they said was at a southside Oklahoma City rental house where four people were found dead early Monday. Police Master Sgt. Gary Knight said firefighters found the bodies about 5:15 a.m. Monday in the house at 1511 SW 56. The fire, which was reported by a neighbor, was set intentionally, Knight said. Knight said the man they are searching for, whose name was not released, is not a suspect at this time. But police have reason to believe he may have information that could further the investigation, Knight said. Knight said Jose Fernando Fierro, 31, who lived in the house, was not one of those who died. The names of the man and three women who died were not released Tuesday. The medical examiner’s office has not made a ruling as to cause of death on any of the victims. A medical examiner’s spokeswoman said autopsies had not been completed Tuesday. Spokeswoman Cherokee Ballard said the medical examiner’s office will be closed today for Veteran’s Day, but more information could be released Thursday. "It is a complex case, and sometimes it takes a while to make positive identification,” Ballard said. Melvin Watkins, whose family owns the home, said he rented the house to Fierro, who had lived there about three months. Anyone with information can call Crime Stoppers at 235-7300.
