Family, friends and co-workers at Bannen Chevrolet in Rivergate released balloons Wednesday in honor of employee Tommy Allen."We wanted to do something to celebrate the time that he was on earth and the time we all knew him," explained Parts and Service Director Dave Johnstone. Allen, 23, died Tuesday morning, more than a month after he was struck by an alleged drunk driver on Demonbreun Street in Nashville.Allen was recovering at a rehab center at the time of his death. His family said he died from complications from his injuries."Last week, last I heard he was doing some better with his eyes open and making some movement, it was a complete surprise, got a call he had passed yesterday morning before I left," Johnstone said. Allen's friend, Michael Brooksher, 22, was also hit in the early morning hours on December 10 and died two days later.Allen worked in Bannen's parts department for five years and according to friends and family, loved his job."He loved cars, loved his trucks. Seems like every few days he was trading trucks and was tricking them out and he did a good job with them," Johnstone said. The balloons released were orange and white in color because Allen was a big fan of the University of Tennessee."He was quiet and loud at the same time. I don't know how else you would describe him, but he was a lot of fun to be around," Johnstone said. Donations to the Brooksher and Allen families can be made at any U.S. Bank to the T and B Foundation.Twenty-three-year-old Trevor Bradshaw was behind the wheel of the car that struck the pair.Police said he ran from the scene following the collision, leaving his wounded girlfriend, Erin Brown, behind. Both Bradshaw and Brown, 21, are charged in the accident.Brown is also charged because Bradshaw was driving her car.According to the arrest report, Brown gave her keys to Bradshaw and allowed him to operate her vehicle knowing he had been drinking that night and was drunk.A preliminary hearing is scheduled for later this month.
