(WBIR) - 
A man faces murder charges after driving his SUV through a crowd at Trails End Campground Saturday after the Trace Adkins concert.

Billy Jason Carson, 42, a vendor at Saturday's event, was intoxicated and started a fight in the area where the concert was being held, according to Keith Hawkins with the Scott County Sheriff's Office. Officers got a call just after 11 p.m. that Carson was threatening people with a gun and running over people.

According to Hawkins, Carson became extremely angry during this fight and came back to his Toyota 4-Runner where he kept a revolver. Carson then drove his car back to the concert area, threatened people with his gun and started spinning his SUV. Witnesses told the sheriff's office that Carson hit an ATV and another car, then ran over four men. 

Tony Farrell was killed during the incident. Farrell was a former monster truck driver. 

Monster Jam released a statement on their Facebook page saying: 

"It is with profound sadness that we share the news that former Monster Jam driver and friend to many of us at Feld Motor Sports, Tony Farrell, passed away this holiday weekend. From his driving team, to the mechanics, to all of us, Tony's dedication to Monster Jam was immeasurable. He will be remembered not only for his skill as a driver but as a mentor for so many who would not have risen to the challenge without his patience and support. Our thoughts and prayers are with his family during this difficult time. Tony will be missed but always remembered."

Event security detained Carson after another person rammed into his 4-Runner with a Jeep to stop the rampage.

Carson appeared before Scott County Judge Jamie Cotton Tuesday, who said due to the holiday weekend, he wanted to see him without unnecessary delay.

Judge Cotton postponed the arraignment until Wednesday to give Carson more time to discuss hiring an attorney with his family. Carson was confused over the court appearance date and told the judge he hadn't slept since Saturday due to the stress.

Carson is charged with homicide and felony reckless endangerment. His bond is set at $500,000.
