Raleigh, N.C. — A Raleigh man charged with first-degree murder in a weekend death went to a nearby church Sunday morning, saying he assaulted his girlfriend and that he thought she might be dead, according to a 911 call released Monday evening.

Wedjunald Gemeille, 21, of 201-20 Loft Lane, was arrested Sunday and charged with first-degree murder in the death of Angel D. Irby, 29, who lived at the same address.

Investigators have not released any details about their investigation into Irby's death, including a motive or how she died.

Police, however, did release a 911 recording made at 10:15 a.m. Sunday in which the caller, a retired police detective, asks the dispatcher if anyone reported an assault at Gemeille's address overnight.

"I have a young man with me," the caller said. "He came into our church, and he indicated that he assaulted his girlfriend at his apartment and that she could possibly be 103."

The number, 103, is a police code that indicates someone has been killed.

"We're trying just to confirm that, if you could get a unit to go by that address," the caller said.

Gemeille, police said, was detained without incident at the church, The Fountain of Raleigh at 9621 Six Forks Road.

He was being held in the Wake County jail without bond Monday evening and was scheduled to make his first court appearance Tuesday.

According to court records, Gemeille is also awaiting trial on misdemeanor charges of assault on a female and assault inflicting serious injury stemming from a November 2012 incident. Details surrounding that case, however, are unclear.

He was also arrested in July 2010 and charged with murder in connection with the death of Pier Munoz-Chinos, 31, of Raleigh.

Gemeille's former defense attorney, Mary Jude Darrow, however, said prosecutors dismissed the murder charge after evidence showed Gemeille was not involved but rather tried to stop a fight that led to Munoz-Chino's death. The arrest was subsequently expunged from his record, she said.

Irby had recently moved to Raleigh from Chicago, according to friend Alicia Williams, and was studying business administration with the hopes of one day opening up her own day care.

"She was a beautiful person inside and out," Williams said. "She had a sweet demeanor about her, a nurturing demeanor, and she always cared about helping other people."

Williams said Irby had come to her home in recent months claiming that Gemeille had hit her but that Irby urged Williams not to call police.

"It's a shock that this happened," Williams said.
