Patterson man accused of murdering girlfriend faces trial

Marcus Hamilton


The trial for a 20-year-old Patterson man accused of killing an 18-year-old woman in January 2013 in Bayou Vista is scheduled to begin Monday.
Marcus Jay Hamilton, 20, of the 1700 block of Guyther Street in Patterson, was charged with second degree murder Feb. 28, 2013, in the apparent shooting death of Keyiona Chenevert, 18, of Bayou Vista.
According to the affidavit for Hamilton’s arrest, on Jan. 21, 2013, the St. Mary Parish Sheriff’s Office began investigating a homicide in the 100 block of Three B’s Lane in Bayou Vista.
Investigators determined that Chenevert had been murdered by a single gunshot wound to the back of the head, the affidavit said. Investigators discovered Chenevert and Hamilton had a physical relationship, the affidavit stated.
While being interviewed, Hamilton told investigators that the day of the murder, he and Chenevert exchanged several phone calls and text messages, the affidavit said. In the communications, Chenevert had informed Hamilton she was pregnant and wanting to end the relationship, according to the affidavit.
The Acadiana Crime Lab determined that the round used to murder Chenevert was from a .45 caliber pistol, the affidavit said. Another man who investigators interviewed said Hamilton called him and asked to borrow his Taurus pistol “to do a lick,” according to the affidavit. The man said Hamilton came to his home and picked up the pistol, which was fully loaded, the affidavit said.
The man said that Hamilton returned the gun Jan. 21, 2013, with two shell cases missing from the gun, the affidavit said. The man told authorities that after Hamilton returned the gun, he believed Hamilton had murdered Chenevert, the affidavit said. The man said he began trying to keep distance from Hamilton because he was scared Hamilton would kill him, the affidavit stated.
