Boston Police Commissioner Edward F. Davis said there appear to be no connections among four shootings across the city Saturday, including one that left a man dead in Roslindale.
In the other three shootings, one man was critically wounded and six people were injured.
“They seem to be different situations,” Davis said in an interview Sunday.
The shootings occurred within a 24-hour period and were spread across the city. Davis said police had solid leads in three of the incidents but so far had made no arrests.
A ninth person was shot late Sunday afternoon in Franklin Park. He was wounded in the shoulder and is expected to survive, police said.
Saturday began with shots fired just after midnight near the Stadium Sports Bar & Grill in South Boston and the discovery of a man with apparent gunshot wounds on nearby Dorchester Street, police said.
A second man, found in Jamaica Plain, told police he was also shot near the bar, police said. Both were expected to survive.
A third man sustained life-threatening wounds but found his way to Boston Medical Center, where police said he was in critical but stable condition.
Davis said the shooting occurred in the parking lot but appeared to have begun as a scuffle inside the bar.
He said detectives were reviewing video from the bar and hoped to release an image to help identify the suspect.
About 15 minutes after the South Boston shooting, two women told police they were shot on McGreevey Way in the Mission Main public housing development in Roxbury. One woman’s back was grazed, police said, and the other had a wound at her right elbow.
Davis said one of the women was carrying a large amount of crack cocaine, and the shooting appeared to be drug related.
At about 1 p.m. Saturday, officers located a man who appeared to have been shot in the foot on Elm Hill Avenue in Roxbury, police said, and a wounded woman near Cheney and Montana streets. Both were expected to survive.
Davis said the afternoon shootings appeared to be connected to the Saturday funeral of Jody Hargrove, who was fatally shot one week earlier near Blue Hill Avenue.
Saturday’s fourth and final shooting was its most deadly.
Just before midnight, officers responded to 80 Archdale Road in Roslindale’s Archdale Village public housing development and found a man in a parking lot suffering from gunshot wounds, police said.
The man was pronounced dead at the scene, the 36th homicide in Boston this year, police said. Police did not release his identity pending family notification.
The shooting took place about 300 yards from the site of the city’s third homicide of the year. Carly Jones was shot in her apartment on Fawndale Road in Roslindale on Jan. 29.
Davis said the man killed in Roslindale late Saturday was involved in an ongoing conflict and had previously reported that his car’s tires had been slashed, among other incidents.
“He clearly had a dispute with someone, and we are trying to drill down into that to find out what was going on,” Davis said.
Davis said residents in the Archdale Village area are often reluctant to aid investigations. He called on members of the public to come forward with any information.
Just before noon on Sunday, a police cruiser idled outside 80 Archdale Road with a single officer seated inside. Bobby Cowart sat on a nearby bench, observing as his neighbors went about their Sunday activities.
Cowart said he did not hear the gunshot that killed the man, but he and another neighbor, who only gave her first name, Cathy, said they heard a long barrage of gunfire later in the night.
Police could not immediately confirm whether shots were reported in Roslindale early Sunday.
Cowart, 66, said he has lived in Archdale Village for 27 years. He said there was a period of violence in the early 1990s, but it had since been peaceful until the past two or three years.
Cowart said troublemakers had moved into the development.
“If you put a bad apple in a barrel of good apples, they’re going to rot them and spoil them,” he said.
Cowart said he was concerned that police patrols of the development seem cursory and officers rarely patrol on foot.
Davis acknowledged that violence had been an issue in the development but said it was sporadic and that police had increased efforts to make the neighborhood safe.
“We’ve assigned two bicycle officers there in the recent past and a sergeant to increase visibility in that district,” he said.
Suffolk District Attorney Daniel F. Conley, who is running for mayor of Boston, said that while the city sees periodic spikes in violence, such incidents are on the decline. He said, though, that it was unusual to see violence spread out across the city.
“We always worry about hot-spot neighborhoods of Boston where we tend to see shootings,” he said. “When you see three neighborhoods impacted this time . . . it is disconcerting.”
Other mayoral candidates also spoke out.
City Councilor Rob Consalvo, whose district includes Archdale Village, released a statement saying violence is “all too common” in some parts of Boston.
“It can be easy for us to think that the effects of localized gun violence are limited to certain neighborhoods, but it is a citywide problem that demands a citywide solution,” he said.
