Wilvin Guity, a 28-year-old Dorchester man, has been charged with the shooting deaths of 23-year-old Christopher Joyce and 58-year-old Clayborn Blair on May 4 in Jackson Square, according to the Suffolk County District Attorney’s (DA) Office.

Joyce was a college student who would have graduated last weekend, while Blair was a father of three.

Guity was arraigned in Roxbury Municipal Court on May 14 for two counts of murder and a single count of unlawful possession of a firearm. Judge David Weingarten ordered him held without bail at the request of Assistant District Attorney John Verner.

According to the DA’s Office, surveillance cameras on May 4 captured a white Ford Fusion arrive in the area of Chestnut Avenue and a man exit the rear passenger’s side door. He walked into the Mildred C. Hailey Apartments and opened fire on a group of about 15 people. He then ran back to the car and fled the area. The man was later identified as Guity because of his distinctively patterned sneakers, according to the DA’s Office. The same sneakers were found at Guity’s home after Boston Police executed a search warrant there, according to the DA’s Office.

Guity, who is represented by William White, is slated to return to court on June 13. White said he had no comment on the case.
