Witnesses told officers Murray said he wanted to cool off while he was forcing him way into the occupied vehicles.
“We believe that he was possibly suffering from the effects of some sort of narcotics, but we will, again, have to wait for the medical examiner makes the determination,” Nelson said.
The homicide unit is conducting a criminal investigation, and internal affairs will review the investigation, Nelson said.
Man had criminal past
Murray was convicted of driving a motor vehicle while under the influence of alcohol and assault and battery on a police officer in January 2011 in Payne County, according to the state Corrections Department website. He was released from prison in March.
Murray also was arrested on drug complaints and public drunkenness complaints, according to Payne County court documents.
Nelson said Murray had no record with Oklahoma City police before Saturday's incident.
