New Orleans homicide detectives said Tuesday that they have obtained an arrest warrant for a transgender woman suspected of killing another transgender woman with a black-market silicone injection.

Armani Nicole Davenport, who was born Larry T. Bernard, is wanted on a count of negligent homicide for allegedly injecting Brenisha Hall, 25, with the silicone in October.

Detectives on Tuesday went to a home Davenport has in Baton Rouge but did not find her there.

The transgender entertainer, who travels among a circuit of gay pageants, is believed to be living in Dallas, said Officer Frank Robertson, an NOPD spokesman.

Hall’s death initially was incorrectly determined to be natural, despite the introduction of chemicals that poisoned her body.

Hall, 25, who was born Brad, was hospitalized after receiving the injections to her hips and buttocks and fell into a coma.

Police booked Davenport, 33, with negligent injuring after the Oct. 24 incident.

After regaining consciousness for several weeks, Hall died Jan. 1, but her death initially was classified as natural.

Despite an open criminal investigation into the matter, officials at Interim LSU Hospital failed to notify New Orleans police or the Orleans Parish Coroner’s Office about Hall’s death. Instead, because Hall lived on the West Bank of Jefferson Parish, they contacted the Jefferson Parish Coroner’s Office, which was not aware of the circumstances surrounding her hospitalization.

The Jefferson office determined the death was natural because it did not involve a suicide or an accident, and the body was incorrectly released to the hospital for an autopsy.

Jefferson Parish Coroner Dr. Gerry Cvitanovich has said his office would not have ruled on the death if it had known about the NOPD investigation.

It was not clear why Interim LSU Hospital officials did not notify authorities in New Orleans about the death.

In fact, Orleans Parish authorities learned about Hall’s death only when The New Orleans Advocate notified them about it, a day before she was buried.

Hall’s family protested the classification of the death as natural, saying that doctors at the hospital told them the death was related to the injections — likely of Fix-A-Flat — she received.

Attempts Tuesday to contact Hall’s mother were unsuccessful.

After learning it had inappropriately autopsied Hall, Interim LSU Hospital turned over its documents and autopsy reports to the Orleans Parish Coroner’s Office, which last week ruled the death a homicide.

John Gagliano, the coroner’s chief investigator, said a review of medical documents led a forensic pathologist to determine Hall died of complications from injections of a silicone-like substance. The substance was found throughout her body, including her brain, Gagliano said.

Homicide detectives Nick Gernon and Theo Kent are in charge of the investigation.

Anyone with information on Davenport’s whereabouts is asked to contact Gernon or Kent at (504) 658-5300 or Crimestoppers at (504) 822-1111.
