A Dorchester man was held without bail on a murder charge stemming from the shooting death last month of 25-year-old Aaron Wornum in Dorchester, Suffolk County District Attorney Daniel F. Conley said today.
Assistant District Attorney David Fredette of Conley’s Homicide Unit today recommended that ANTHONY ROBERTSON (D.O.B. 5/19/91) be held without bail pending trial; Dorchester District Court Judge Rosalind Miller granted that request.

Fredette told the court that the victim and defendant were known to one another. Phone records obtained by investigators suggest the victim was on his cell phone just before the June 26 shooting, Fredette said, and additional investigation has linked the other phone to the defendant.

Wornum was shot multiple times near the intersection of Sumner and East Cottage streets at about 9:00 that night. He was transported to Boston Medical Center where he died of his injuries.

On Tuesday, amid the ongoing and at times around-the-clock investigation, prosecutors approved a warrant charging Robertson with Wornum’s murder. Late yesterday, members of the Boston Police Fugitive Unit and Youth Violence Strike Force apprehended him at an Arbutus Street residence.

Wornum is represented by attorney James Greenberg. He will return to court on Aug. 15.
