A Mississippi man will spend more than five years in federal prison after pleading guilty to assaulting his wife by kicking her with steel-toed boots, fracturing her ribs.

According to the U.S. Attorney’s Office and court documents, Lee Garrick McMillan assaulted his wife in May on the Choctaw Indian Reservation in Pearl River County, Miss. Both McMillan and his wife are Choctaw Indians.

The initial indictment charged McMillan with assault with a dangerous weapon (the boots); assault resulting in serious bodily injury; assault by strangulation; and domestic assault by a habitual defender.

The U.S. Attorney’s Office said this was McMillian’s third domestic violence incident.

McMillian was indicted by a federal grand jury in early June and initially pleaded not guilty, but in August he withdrew that plea and accepted a plea agreement with prosecutors.

Under the agreement, McMillian pleaded guilty to assault with a dangerous weapon and domestic assault by a habitual defender. In exchange, prosecutors dropped the other two charges.

McMillan’s 63-month sentence was handed down in U.S. District Court in Jackson, Miss., Wednesday. He had been facing up to 10 years on each of the two counts to which he pleaded guilty, as well as up to $500,000 in fines.

The case was investigated by the Choctaw Police Department and the FBI.
