A Suffolk Superior Court jury today convicted a Chelsea man of stabbing his mother’s boyfriend to death during a melee inside their Chester Avenue home two years ago, Suffolk County District Attorney Daniel F. Conley said today.

EUGENE TEIXEIRA (D.O.B. 3/25/87) was convicted of manslaughter for the April 29, 2008, stabbing death of 25-year-old Cleo “Shadeed” Wiggins. Jurors acquitted Teixeira’s brother, AASIM SMITH (D.O.B. 4/13/92), of his role in the incident.

Prosecutors had argued during the two-week trial that Teixeira fatally stabbed Wiggins and that Smith, who allegedly wielded a baseball bat but was kept away from Wiggins by a family friend, shared his deadly intent.

Assistant District Attorney Cory Flashner proved that Teixeira stabbed Wiggins seven times after he and Smith were ejected from the apartment by their mother, with whom Wiggins had a romantic relationship. Flashner disputed claims that they acted in self-defense or defense of any other person.

Superior Court Judge Patrick F. Brady will sentence Teixeira at 2:00 Monday afternoon in courtroom 815.

Catherine Yuan was the DA’s victim-witness advocate on the case. Smith was represented by attorney Stephen Weymouth and Teixeira by attorney George Murphy.
