A La Vergne police officer is on routine administrative leave after he was forced to open fire on a domestic assault suspect Wednesday evening.The officer responded to a domestic violence call around 5 p.m. at the Cedar Glen trailer park located off Sand Hill Drive and Bill Stewart Road.Upon arrival, he found a woman who had been assaulted."She was obviously in fear of great bodily harm or her life," said La Vergne Police Chief Mike Walker.The suspect, who had fled the scene, was located on Murfreesboro Road about 10 minutes later.Officers tried to pull him over, but the man refused to stop. The suspect eventually began driving back to the mobile home park. As he approached the residence, he accelerated at a high rate of speed toward an officer still on the scene.The officer fired one shot at the man's car in an attempt to stop him."The guy kept making threats of harming himself or harming others," explained Walker, adding, "He had already tried his best to hurt her and she was able to get away from him."When the suspect got out of his vehicle, he attempted to commit suicide. The suspect was transported to Vanderbilt University Medical Center where he remained Thursday afternoon. "I've got grandkids," said Randy Comb, who heard the gun shots, "I've got five grandkids and it's like do you even want to live here anymore?"No officers were hurt in the incident, which is something Walker said he's especially grateful for, given how the situation easily could have ended in tragedy."I closed my eyes and thanked the good Lord about twice last night," said Walker.The Tennessee Bureau of Investigation is conducting an investigation.The officer who fired the shot was placed on routine administrative duty pending the outcome of the investigation."I don't really see anything so far about the whole circumstance that we could've done anything any differently," Walker told Nashville's News 2. The suspect, whose name wasn't immediately released, faces several charges, including domestic assault and evading arrest.
