Boston Police arresting a Mattapan man on Monday in connection with a breakout of gunfire on Saturday afternoon that left Eleanor Maloney, a 74-year-old grandmother, dead at the scene on Mattapan Street. Police say she was an innocent bystander who had nothing to do with the cause of the gunfire.

Anthony Davis, 37, one of two men also shot in the drive-by, was arraigned Monday afternoon in a hospital room at Brigham and Women’s Hospital, where he is currently a patient, on charges of unlawful possession of a firearm, fourth offense, and being an armed career criminal, the Suffolk County Attorney’s office reported.

Dorchester Municipal Court Judge Thomas Kaplanes set bail at $50,000 – and ordered that Davis wear a GPS monitor should he make bail. Davis was not charged with Maloney’s murder; had he been, he would have been ordered held without bail.

Suffolk County District Attorney Rachael Rollins told reporters that she had spoken with Maloney’s family, according to WBUR. “One of them said, ‘We’re sick and tired of prayers,’ and they’re absolutely right,” Rollins said. “They deserve accountability. We have to work harder to make sure that we have a plan about violence.”

Boston Police Commissioner William Gross also weighed in on the shooting, reported WBUR. “Our neighborhoods are better than this,” he said. “This is a time that we bond together and show people that this should not be tolerated.”

Police say they are continuing to investigate the drive-by shooting. Anybody with information can contact homicide detectives at 617-343-4470 or the anonymous tip line by calling 800-494-TIPS or by texting TIP to CRIME (27463).
