Boston police on Saturday arrested a 22-year-old Hyde Park man they say shot and killed a man and wounded a woman last weekend in Dorchester.

Aaron Almeida was arrested in the area of Morrissey Boulevard and Neponset Avenue in Dorchester at about 10:45 a.m.

Almeida is accused of killing Ailton Goncalves, 35, of Dorchester, and wounding a 31-year-old woman, in the street outside of 6 Dudley Terrace at about 12:05 a.m. last Saturday. Police found the victims after the city's ShotSpotter was activated, officials said at the time.

Goncalves was pronounced dead at the scene; the woman is expected to survive her injuries.


Witnesses to the shooting reported a man in a blue hoodie running from Dudley Terrace and taking a left on Dudley Street headed toward Columbia Road, officials said last week.

Almeida is scheduled to be arraigned Monday in Dorchester District Court on charges of murder and unlawful possession of a firearm.

Police are still investigating the killing, and ask anyone with information to call the Homicide Unit at 617-343-4470. Anyone who wants to pass along a tip anonymously can do so by calling the CrimeStoppers Tip Line at 1-800-494-8477, or texting the word "TIP" to 27463.
