A 22-year-old who was being detained following a fatal shooting Saturday in Mansfield, Massachusetts, is now facing weapons charges, officials announced.
The Bristol County District Attorney's Office said Sunday that William O'Brien, of Manchester-By-The-Sea, is being charged with carrying an illegal firearm and carrying a loaded illegal firearm.
O'Brien had been detained Saturday during the initial investigation into the homicide that occurred at a home on West Church Street near Rumford Avenue.
Police were called to the home around 11:10 a.m. after someone called 911 to report a shooting. Once on scene, first responders found the victim had been shot to death. He was later identified as Samuel Waters, of Mansfield.

Investigators were at the Mansfield home for much of the day Saturday, taking photos inside, going in and out of the home as they searched for evidence, and crime tape was blocking off part of the road as neighbors looked on in disbelief.
"We're shocked. I mean, this doesn't happen in Mansfield," Mark Shachat said.
"I was not home, I just came back and saw a lot of police," another neighbor shared. "Surprised in this town it happened, that incident."
Alyse Carmichael says she was about to take her dogs out when she heard yelling.
"Heard a young kid kinda running down the street screaming, he was pretty upset, something about somebody got shot, we weren't really sure what was going on," she said. "It's scary but also, it can happen anywhere. Doesn't really matter where you live or what part of town. Just gotta keep your eyes out."
Other neighbors told NBC10 Boston that the shooting has them on edge, knowing it happened so close to their homes.
"Yeah I mean, I didn't think it was going to happen in Mansfield of all places," Shachat said. "You always hear about it in other towns."
An investigation into the fatal shooting is ongoing.
