A man was gunned down outside a Mattapan triple-decker in a brazen afternoon shooting Wednesday, sparking a lengthy foot chase that ended with police apprehending a suspect.
The victim, who is in his 20s, was shot in the chest on Fessenden Street shortly before 2 p.m., and suffered injuries that were not considered life-threatening, Boston police said in a posting on the department’s website.
Investigators placed seven markers indicating the location of shell casings on Fessenden Street, which runs off Blue Hill Avenue.
After the shooting, police officers approached a man who matched a description they had of the suspect, and he took off running.
The man ran through backyards and jumped a number of fences before officers caught up to him on Hosmer Street, the Police Department’s superintendent-in-chief, William Gross, said from Fessenden Street, where investigators interviewed residents and families looked on from their porches.
Officers arrested Patrick Bishop, 22, of Boston, and charged him with assault with intent to murder, unlawful possession of a firearm, and unlawful possession of ammunition.
“We do believe this is an isolated incident,” Gross said.
He also said that officers were investigating what led to the shooting.
The superintendent-in-chief praised the arresting officers, who were on patrol in the area before rushing to the scene of the shooting, for successfully apprehending the suspect.
One witness, who declined to provide her name, said she heard several gunshots ring out, and initially hoped they might be fireworks. But then she heard the sirens.
Within minutes, several police cruisers had arrived on Fessenden.
“It’s crazy,” she said. “It’s usually pretty quiet around here.”
Gross urged anyone with information about the shooting, which took place just up the hill from a playground, to notify authorities.
“No bit of information is too small,” he said. “Quite frankly, everyone’s tired of these acts of violence.”
Some neighborhood residents returned to find the street blocked off by investigators, and asked police whether they could be let through to get home.
