Boston Police report arresting a Mattapan man in connection with the Saturday triple shooting on Mattapan Street that left Eleanor Maloney, 74, dead.

Anthony Davis, 37, one of the two men also shot in the drive-by, was arraigned this 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 reports. Dorchester Municipal Court Judge Thomas Kaplanes set bail at $50,000 - and ordered that he wear a GPS monitor should he make bail.

Maloney, police say, was an innocent bystander who had nothing to do with the reason behind the gunfire.

Davis was not charged with Maloney's murder; had he been, he would have been ordered held without bail.

In February, 2014, Davis was sentenced to six years in state prison - with a year taken off for the year he'd spent awaiting trial - on a charge of illegal possession of a firearm following his arrest during a traffic stop the year before.

This followed a three-year prison sentence on a 2010 gun charge and a one-year jail sentence for a similar 2004 arrest. He was also convicted in 2002 for assault and battery and in 1999 for possession of heroin with intent to distribute, according to the Suffolk County District Attorney's office.

Police add 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).
