Investigators found forensic evidence at the scene that led them to Bennett, Parrish said.
Bennett allegedly approached and tried to rob Hough about 7:45 p.m.
“He resisted the suspect’s attempt and a struggle ensued,” Parrish said. “At that time, Mr. Hough was shot while sitting inside his vehicle, twice in the torso.”

Hough was a well-known businessman in North Georgia. An Air Force veteran, his successful business developed and operated food courts in malls and airports nationally, Channel 2 reported Friday.
He was also known for his philanthropic work.
“Very giving, any charities that needed help he would be glad to help,” Kevin Wetzel, the president of a local funeral home who knew Hough for 20 years, told Channel 2. “Just did a lot for a lot of people."
His family asked that in lieu of flowers, donations be made to two of Hough’s favorite Gainesville charities: We Care and the Gainesville First United Methodist Church.
“This community lost a wonderful man,” Parrish said, adding that he spoke to Hough’s family following the arrest. “It takes that cloud off of them as they begin their own healing process.”
