A Suffolk Superior Court jury late this afternoon convicted a Dorchester man of all charges for his role in a 2007 Maynard Street shooting that resulted in the death of 21-year-old Fausto Sanchez and serious injuries to two of Sanchez’ friends, Suffolk County District Attorney Daniel F. Conley said.

Jurors convicted EMMANUEL DASILVA (D.O.B. 10/24/84) of first-degree murder and multiple counts of armed assault with intent to murder, assault with a dangerous weapon, and assault and battery with a dangerous weapon for shooting at Sanchez’ four friends, striking two of them, on Feb. 13, 2007. One of the surviving victims was left permanently disabled from gunshot wounds sustained to his back, side torso, and left arm.

Dasilva faces a mandatory life term without the possibility of parole when he is sentenced at 10:30 Monday morning.

Assistant District Attorneys Julie Higgins and Mark Zanini proved that the Dasilva and his uncle, JOSEPH GOMES (D.O.B. 4/20/67), were looking for another man whom they believed was responsible for firing shots in the area of Dasilva’s Langdon Street home.

Neither Sanchez nor his friends were involved in that incident, the evidence showed, but they happened to be standing in the vicinity of that man’s residence when Dasilva and Gomes rode up in a silver 2006 Chevrolet Impala at about 6:00 p.m. With Gomes behind the wheel and Dasilva in the front passenger’s side seat, they came to a quick stop near 39 Maywood St., lowered the window, and fired a volley of shots at the group of men before speeding away. Sanchez was mortally wounded and died of his injuries.

“With this conviction, I hope Mr. Sanchez’ family can find some sense of satisfaction that justice was done on his behalf,” Conley said. “The evidence in two trials proved conclusively that Fausto died through no fault of his own and no action he took. He died because two men bent on revenge and retaliation opened fire on a group of friends who had the temerity to talk and socialize on a city street. There’s no excuse for that violence and no justification for the mindset behind it. With first-degree convictions for this defendant and his uncle, justice has finally been done.”

The Gomes and Dasilva were stopped minutes after the shooting about a block away by a quick-thinking Boston Police detective who had heard a description of the suspect vehicle. When Gomes and Dasilva exited their Impala, investigators recovered six spent shell casings inside, including two on the front passenger’s seat. Those casings were ballistically matched to a seventh casing found at the scene.

A different jury last year convicted Gomes of first-degree murder for his role in the shootings. He was sentenced to life in prison without the possibility of parole and a consecutive sentence of 17 to 18 years in prison for the attempted murder of a surviving victim who remains disabled from the attack.

Gomes and Dasilva went to trial together on Nov. 15, 2010. Their cases were severed on Dec. 1, when Dasilva’s attorney took ill and his case was declared a mistrial.

Jennifer Sears is the DA’s assigned victim-witness advocate. Dasilva was represented by attorney Timothy Bradl. Judge Frank Gaziano presided in courtroom 906 of Suffolk Superior Court.
