The Winslow man police say gunned down another man outside a Waterville bar last night made his first appearance in court this afternoon. 30-year-old Matthew Partridge is charged with murder. Partridge showed no emotion and did not speak as a Waterville judge ordered him to be held without bail. Police say Partridge shot and killed 26-year-old Justin Smith of China last night and authorities are still trying to piece together exactly what led up to the shooting.It happened just after 11:00 Tuesday night at You Know Who’s Pub in downtown Waterville. Police say an altercation involving Smith and Partridge started inside the bar and spilled out into the Concourse area. One eyewitness said Partridge went to his truck to get a gun and, despite attempts to stop him, shot Smith. Waterville and Winslow police responded to the call within minutes but they were too late. “We did locate one male individual who appeared to have been shot that was lying outside on the Concourse and he was taken to the hospital and shortly after that he was pronounced dead,” Waterville Police Chief Joe Massey told reporters Wednesday morning. Waterville Police and dispatch immediately put out a description of Partridge’s pickup truck to area law enforcement. “At 11:26 a Maine State Trooper spotted a vehicle that matched that description on Route 8 in Smithfield. The vehicle also had a headlight out. A traffic stop was affected and it was determined that vehicle was the one involved in the shooting,” said Lieutenant Chris Coleman of the Maine State Police Major Crimes Unit.Coleman said Partridge was alone when he was arrested and was taken into custody without incident. Police say the case is still under investigation. Coleman said the suspect’s truck is being analyzed at the Maine State Police Crime Lab. An autopsy will be performed this afternoon on Smith. After the hearing, Partridge was transported to the Kennebec County Jail.
