LAFAYETTE — The 31-year-old Broussard man accused in the beating death of his girlfriend’s 9-year-old son has an extensive criminal history involving theft, drugs and domestic violence, according to court records.

The Lafayette Parish Sheriff’s Office arrested Ronjoerox Hamilton on Sunday on one count of first-degree murder.

Hamilton brought the boy, whose identity has not been released, into Women’s & Children’s Hospital in Lafayette late Saturday night.

The boy was not breathing and had suffered significant injuries throughout his body, the Sheriff’s Office has said. He died Sunday afternoon.

It is unclear how long the boy had been in Hamilton’s care. Lt. Craig Stansbury, spokesman for the Sheriff’s Office, said that is under investigation.

Records at the Lafayette Parish Courthouse show that Hamilton has been arrested at least 15 times since 1997 on charges that include unauthorized use of a moveable, aggravated criminal damage to property, possession with intent to distribute cocaine and marijuana, illegal carrying of a firearm in the presence of a controlled dangerous substance, domestic abuse battery, issuing worthless checks and multiple counts of theft.

Five of the cases, including the domestic abuse battery charge, were dismissed.

The longest sentence Hamilton ever received was in 1999 when he was sentenced to serve five years for illegally carrying a firearm in the presence of illegal narcotics.

A judge sentenced him to five years with credit for time served and allowed him to serve his time in a halfway house, court records show.

Hamilton was last charged in August 2009 with possession of marijuana. He was found guilty and sentenced to five months in prison, with all but seven days suspended, court records show.

In April 2004, the first of two women filed for a protective order against Hamilton.

Lisa Marie Smith wrote in the petition that Hamilton “choked me with both hands” during an argument. “He said he was gonna kill me. He stole my car and then called me and told me where it was,” she added.

She wrote that Hamilton “is really abusive — blacked my eyes, busted my lips during this past year.”

The protective order was dismissed later that month at Smith’s request, court records show.

Two years later, Rachelle Lynn Pennington filed for protection from Hamilton’s alleged abuse.

Pennington wrote in the August 2006 filing that she “was choked by the defendant for ‘talking smart’ to him.”

She wrote that she also had received a threatening voice mail from him and that he had kicked her in the ribs and choked her several times.

The petition was dismissed in September 2006 when Pennington failed to appear, court records show.
