A Jefferson Parish grand jury added weapons charges Thursday to two separate cases — the fatal double shooting of a man and his transgendered lover in early 2013 in Metairie and a rape and human trafficking case involving two Mississippi men accused earlier this year of forcing women into prostitution in Harvey.

Melvin Miller, the Baton Rouge man accused in the double shooting, now faces gun charges tied to an earlier conviction for a burglary of an inhabited dwelling there.

He’s in Jefferson Parish Prison awaiting trial on two counts of second-degree murder in the killing of Akeem Boudreaux and Morris Williams, who also went by the names “Milan” and “Mimi.”

The decomposing bodies of Boudreaux, 22, and Williams, 26, were found by friends in their Edenborn Avenue apartment. They had been shot in the head Feb. 5, nine days earlier, and their dog had been trapped inside with the bodies.

Miller’s lover, Joseph Alexander, also transgendered and going by the name of “Jasmine,” has been charged with obstruction of justice for allegedly tampering with the scene.

Miller, 23, was found with Williams’ car a week after the murder, and investigators say Miller called Williams several times before going to Metairie to meet her the night of the murder.

The case will be heard by 24th Judicial District Judge Scott Schlegel. No trial date has been set yet.

In the human trafficking case, Willard Anthony, 19, had a gun charge added to the raft of charges against him stemming from an incident that began April 11 in Florida and ended in a Harvey motel.

Anthony, who has prior convictions for aggravated assault and vehicle burglary, is accused, along with Pierre “Bruh” Braddy, of beating and drugging three women and forcing them into prostitution.

Undercover detectives working a prostitution bust on April 16 found one of the women bruised and held captive in a motel on Manhattan Boulevard.

Anthony, 19, faces counts of aggravated rape, sexual battery, aggravated battery and trafficking besides the new gun charge.

Braddy, 26, faces counts of rape, trafficking and obstruction of justice.

Both men are being held in Jefferson Parish Prison.

The three women were 22, 24 and 26 years old.

The case will be heard by Judge Nancy Miller.
