Two men charged in separate homicides this June remain held without bail following their indictments last week and their Superior Court arraignments today, Suffolk County District Attorney Daniel F. Conley said.

ANTHONY ROBERTSON (D.O.B. 5/19/91) of Dorchester was formally charged this morning with first-degree murder for the June 26 shooting death of 25-year-old Aaron Wornum. Just a few hours later, LAQUAN MILLER (D.O.B. 5/25/94) of Roslindale was charged with the same offense for the June 5 shooting death of Wilfredo Martinez, 23, and the non-fatal shooting of a second 23-year-old man during the same incident.

Acting on requests by Assistant District Attorney Davide Fredette of Conley’s Homicide Unit, Clerk Magistrate Connie Wong kept in place orders that both men be held without bail as they have been since their previous arraignments in district court.

Speaking at Robertson’s arraignment this morning, Fredette told the court that Wornum and Robertson were known to one another. Wornum had been on his cell phone with a person he was supposed to meet at about 9:00 on the evening he was killed, Fredette said, and phone records show that person to be Robertson.

At about that time, Robertson allegedly drove up to the scene, exited his car, and pulled a gun. He allegedly shot Wornum multiple times, killing him, and stole a gold chain from him.

Just before his death, Wornum is said to have pleaded for his life, saying, “Ant, it doesn’t have to be this way,” or “Ant, you don’t have to do me like this,” Fredette said.

Multiple witnesses have identified Robertson as the shooter, Fredette said.

A few hours later, Fredette recited the facts of the case against Miller, telling the court that Martinez and another man were behind a Brookway Road building shortly after 10:00 p.m. when two other individuals came out from inside that building and opened fire on them. Martinez suffered multiple gunshot wounds and died of his injuries; the second victim survived his injuries but required extensive rehabilitative therapy as a result of them.

Miller was later identified by several individuals as being one of the gunmen, Fredette said. When he spoke to police, Miller allegedly gave multiple alibis that conflicted with one another and the known facts, Fredette said.

The investigation into the identity of the second shooter remains very active even today, Fredette told the court.

Jessica Sheehan is the DA’s victim witness advocate assigned to both cases. Robertson is represented by attorney James Greenberg and will return to court on Oct. 25. Miller is represented by attorney Bruce Carroll and will return to court on Oct. 13.
