Sheriff's deputies went to the Hollywood Casino's hotel in Tunica County, Miss., after receiving a report about a disturbance at about 5:52 a.m. Deputies secured the first-floor hotel room from the outside when a man jumped through the glass window, Tunica County Sheriff's Department Chief Deputy Randy Stewart said.
The man, 34-year-old Nathaniel Yates III, was resisting arrest so he was shocked with a stun gun and handcuffed, Sheriff K.C. Hamp said in a news release.
Brandi Nicole Floyd, 25, was found unresponsive on the floor of the hotel room.
Yates and Floyd are both from Collierville, Tenn. They arrived together at the hotel, said Jeff Strang, a casino spokesman.
Emergency medical responders were summoned to the scene for Yates and Floyd, but the woman was declared dead by the county coroner. The corner referred questions to the sheriff's department.
Tunica County spokesman Larry Liddell said Yates is suspected of "mutilating" the woman, but authorities haven't elaborated on her injuries or the cause of death.
Liddell said deputies used the stun gun after the suspect "became combative." Yates was taken to Baptist Memorial Hospital-Desoto for treatment for cuts and bruises caused by jumping through the window, Liddell said.

Strang said casino operations continued and that no other patrons were in danger due to the situation. He said the casino's manager personally extended his condolences to the victim's family. He referred other questions to law enforcement.
