In the early morning hours of July 25, 2009, 33-year-old Rolando Fuentes was shot and killed in Lawrence, Massachusetts. Prosecutors called the slaying an act of revenge tied to a longstanding feud rather than a random attack. Authorities say the motive dated to an earlier incident at Jose Ruiz’s home, when Fuentes allegedly shot Ruiz’s father in the neck; that earlier episode also resulted in the death of Rolando’s brother, Orlando Fuentes.

Rolando Fuentes had pleaded guilty after that prior incident to assault with a deadly weapon, burglary, and illegal possession of a firearm, and received a seven-year sentence with three years of probation. Following the 2009 killing, Jose Ruiz was arrested and charged with murder; after a five-day trial in Lawrence Superior Court he was convicted of second-degree murder and later sentenced to life in prison, with additional time for weapons offenses.

Does anyone have details about the earlier confrontation or the feud that led to these events?
