On the morning of January 21, 2010, 29-year-old Maria A. Coya DePina was shot and killed in her second-floor Brockton, Massachusetts apartment at 52 Nilsson Street. A male intruder forced entry into the home she shared with her brother. He first shot Jorge DePina in his rear bedroom as he slept; Jorge was found deceased in bed.

Maria encountered the intruder in a hallway while getting ready for work and was shot in the back of the head; she was discovered on the kitchen floor by first responders who arrived at about 9:16 a.m. Autopsies confirmed both siblings died of gunshot wounds to the head. Investigators later linked the crime to John V. Monteiro when ballistics and DNA tied a firearm he had sold to the murders.

Did anyone in Brockton at the time know the DePina family or have information about that day?
