LYNN – Questions continue to linger regarding last week’s City Hall shooting, where a Lynn man managed to wrestle a handgun out of an officer’s holster and used it to take his own life.The morning of Oct. 7, Marc Gaston, 27, of 124 Green St., was said to have assaulted veteran officer Patrick McGuire as he worked a Verizon utility private detail, blindsiding him to the point where he was able to snatch his gun.While Police Chief Kevin Coppinger has refrained from shedding light on how Gaston overpowered McGuire, he did stress that the retention holsters used by officers in the department are routinely inspected and are up to date.”We have the best equipment available, but we’re still going to take a fresh look at it,” he said. “The holsters are still the standard to be used and we did a lot of exhaustive research on them before we purchased them several years ago.”The holsters used are insured to make snatching a gun extremely difficult from the front, rear, top or side. However, despite those safeguards, Gaston was still able to get his hands on the gun.”It is impossible to prevent random acts of violence like that and it was just an unfortunate situation that resulted in a tragic loss of life,” said City Councilor at-large Daniel Cahill. “(That) could happen anywhere in any town or city in America. The whole scenario is just bizarre.”Coppinger met with authorities Thursday to review and discuss preliminary results from the investigation, but was unable to offer up any new details.”Right now I’m waiting on the District Attorney (Jonathan Blodgett),” he said. “Once he gets the final report on the investigation and the autopsy, we’ll know the specifics.”Meanwhile, the troubling incident has city officials wondering what triggered Gaston’s attack.”This is just one of those incidents where someone with what appears to be mental issues snuck up behind the officer and blindsided him,” City Council President Timothy Phelan said. “I guess his (Gaston’s) goal was to take the gun and kill himself.”Despite the severity of the incident, Phelan said he doesn’t believe the matter has anything to do with training skills, saying city officers are already well-equipped to take on any situation.”Lynn police officers are very passionate about what they do and have great leadership,” he said. “We’re lucky to have who we have to protect us in the city of Lynn.”Coppinger noted that officers are routinely trained in self-defense tactics through instructors that are trained and certified by the Massachusetts Police Training Committee. As of now, he said there have been no operational changes made in the department due to the shooting.”Don’t forget, this was a violent struggle,” he said. “We just finished firearms training last week and are gearing up for classroom training.”In light of the shooting, the question of whether officers working details should continue to be armed with guns in an effort to prevent such an event from recurring was immediately shot down by Coppinger.”There is no reason not to have a weapon (while on detail), it’s one of the officer’s tools,” Coppinger said.Calls placed to Mayor Judith Flanagan Kennedy were not immediately returned. McGuire returned to work Tuesday and is said to be doing OK.
