LAFAYETTE — A grand jury on Wednesday returned indictments in two first-degree murder cases, one involving a 9-year-old boy and a second involving a double homicide inside a Lafayette home.

The grand jury charged Ronjoerox Hamilton, 31, with the first-degree murder of 9-year-old Dylan Royer.

Royer’s mother, Stefani Morgan, was charged with principal to first-degree murder, according to the indictment handed up Wednesday.

Hamilton brought the unconscious boy to a local hospital late on the night of June 11, the Lafayette Parish Sheriff’s Office has said.

While treating the boy, hospital staff found the boy had suffered severe injuries. The boy died the following day, the Sheriff’s Office has said.

Deputies did not specify what role Morgan played in her son’s death. The grand jury also charged Hamilton with possession with intent to distribute cocaine.

In a second case, the grand jury indicted Eric Abshire, 49, in the first-degree murders of 67-year-old Lemuel Brown, and his stepdaughter, Lona Carter, 36, both of Lafayette.

Abshire was Carter’s boyfriend, according to an arrest affidavit. The July 27 killing occurred inside Brown’s home on Warren Street.

While police have not disclosed a motive in the killing, an arrest affidavit noted that witnesses told police that Abshire had been at the home the night before and was consuming illegal drugs at the time.

Witnesses said Abshire returned to the home about 6 a.m. the next morning and was seen leaving the home about one minute after two gunshots were fired inside the home, the affidavit says.

The grand jury also charged Abshire with possession of a Schedule IV drug and possession of a firearm in the presence of a controlled dangerous substance.

The grand jury also returned an indictment against Donald Forest Goodman, who is charged with the May aggravated rape of a 12-year-old girl.
