In a 911 call, a Sevier County man admitted to shooting another man following a fight that involved a baseball bat, court documents released Tuesday say.

William G. Muir placed the call about 12:30 a.m. Sunday, after he allegedly shot and killed 36-year-old David Rioja, of Venice, Sevier County sheriff's deputies wrote in a probable cause statement filed in Richfield's 6th District Court.

Muir, 39, also of Venice, was arrested at his home, where police recovered a .38-caliber revolver from an open lunch box in a closet, the documents say.

"Did I kill him?" a handcuffed Muir asked officers as he was led from his home.

Muir, who complained of injuries he received from a bat during in his tussle with Rioja, was taken by ambulance to an area hospital for treatment before he was booked into jail, police say.

On Tuesday, Muir was being held in the Sevier County Jail on suspicion of murder. Bail is set at $500,000.

Formal criminal charges have not yet been filed.

Deputies initially responded to a 911 call from Rioja's family, who live on the same property in separate homes, according to court papers.

The two 911 calls were placed just a little more than a minute apart.

Family members told police that Muir had twice been to Rioja's home. During the first visit, they heard the two men shouting and fighting. The shouting resumed when Muir returned a second time, the documents say, followed by three gunshots and the sound of Muir's departing car.

Rioja's parents found their son bleeding from a single gunshot wound in the chest in the driveway, the document states.

Rioja died at the scene; paramedics were unable to revive him.

Court papers say police found a wooden implement resembling an ax handle lying near Rioja's body. The handle was broken and stained with what appeared to be blood, the papers say.

Police also found broken glass and part of a window frame in the driveway. Officers later discovered the back window of Muir's car had been broken and a piece of window frame was hanging from the window mounting bracket, court papers say.

Muir lives just five blocks from Rioja, but it is not clear from the document what triggered their dispute or how they were acquainted.

Court papers say a woman who lives with Muir told police that Muir had come home that night looking as if he had been assaulted. She said Muir then left the home again, and when he returned he was carrying a gun.
