NAPOLEONVILLE — Three of six men involved in the 2009 home invasion and robbery of an autistic man have been convicted and sentenced and two more are expected to enter guilty pleas late this year, prosecutors said.

Assistant District Attorney Lana Chaney said Wednesday that the victim, 55 at the time the crime was committed, was putting out his garbage on Dec. 29, 2009, when four men and two then-juveniles, ran up and confronted him.

Jeremy Joseph, 22, of Labadieville, held a gun to the man’s head and took him into his garage while others went into the house, ransacked it and took jewelry and other personal belongings, Chaney said.

Joseph later held the man at gunpoint and tried to get him to provide the combination needed to open a locked safe, but the man could not remember it, Chaney said.

“It was a really horrible crime,” she said.

On Oct. 11, Judge Guy Holdridge, of 23rd Judicial District Court, sentenced Joseph to 20 years in prison.

He had pleaded guilty to first-degree robbery March 15, prosecutors said.

Ernest Watkins, 18, of Supreme, was sentenced earlier to three years in prison after pleading guilty to unauthorized entry of an inhabited dwelling, Chaney said.

Onre Batiste, 22, of Labadieville, also has pleaded guilty to illegal possession of stolen things and received five years in prison, Chaney said.

Chaney said two other men involved in the robbery, Dante Batiste, 18, and Tervonta Johnson, no age provided, both of Labadieville, are expected to enter guilty pleas in November or December.

She said a case against a juvenile involved in the robbery is also pending.
