Two men were sentenced Tuesday to up to 30 years in prison for their roles in a 2023 Dorchester shooting that killed a 41-year-old man, authorities said.

On Monday, Dasahn Crowder, 23, of Quincy, and Tyreese Robinson, 21, of Randolph, pleaded guilty in Suffolk Superior Court to manslaughter, unlawful gun possession, and six counts of armed assault with intent to murder in the slaying of Curtis Effee, Suffolk District Attorney Kevin R. Hayden’s office said.

Effee was shot during a street fight shortly before 1 a.m. on Dec. 30, 2023, on Geneva Avenue, prosecutors said.

Investigators found that a third defendant, Patrick Harland, 32, of South Boston, and Effee had gotten into an argument. Harland then sent Crowder a Facebook message, and Crowder replied, “I’m coming,” prosecutors said. Harland then allegedly told others Crowder was on his way with a gun.

After Crowder and Robinson arrived, a fight broke out on the street, and Harland was allegedly seen brandishing a knife and pointing it at Effee, prosecutors said.

Crowder then pulled out a gun and “opened fire in Effee’s direction,” as did Robinson, Hayden said.

“In addition to the victim, there was a crowd of people outside, including a 10-year-old boy and an 11-year-old girl,” Hayden said.

Effe was struck by gunfire and died from his wounds. Prosecutors didn’t specify which gunman fired the fatal shot.

At Tuesday’s sentencing hearing, Effee’s mother told the court she misses her son “every day.”

“I am still in a lot of pain,” Luvenia Effee said. “He had his faults, but I don’t think he should have died that way.”

Judge Mary Ames sentenced Crowder and Robinson each to 18 to 20 years in state prison for manslaughter, to be followed by seven to 10 years on the assault charges.

Ames told Crowder and Robinson there was “depravity” in their actions.

“I hope you see what happens when people come with guns to settle whatever dispute — the finality of the action you take when you take a life,“ Ames said. ”There is sanctity in life.”

“To open fire into a crowd of people, including children, there’s a depravity associated with that kind of action,” she said.

Crowder and Robinson fled the scene in a car and were arrested together the next day. Harland fled on foot and was arrested March 25, 2024.

Hayden said the two guilty pleas and the upcoming prosecution of Harland “demonstrate that everything possible is being done to secure justice for Curtis Effee and his family and to make clear that this type of violence which hurts our neighborhoods and communities will not be tolerated.”

Officials said Harland is scheduled to stand trial on murder and gun charges Aug. 10.
