Baton Rouge police arrested the 52-year-old man wanted in the fatal shooting of his 41-year-old ex-girlfriend after an almost four-day search for the suspect, police spokesman Sgt. Don Coppola said.

Police say Robert Antoine, 4665 Shelley St., turned himself in Tuesday. Antoine is accused of shooting Monique Maxie as she got out her vehicle with a friend early Saturday. Maxie died almost a day after the shooting.

She was shot multiple times, said Beau Clark, East Baton Rouge Parish coroner.

"I'm relieved that he's off the streets, but at the same time, I can't get my sister back," said Niette Maxie, Monique Maxie's sister.

Police said Monique Maxie and Antoine were at the same party Friday, but Antoine was kicked out by security after he made threats against her.

When Maxie and a friend left the party to drive home, Antoine followed them, Coppola said. 

"They noticed they were being followed," Coppola said. "Once they exited the vehicle, shots were fired."

Only Maxie was hit by gunfire, but Antoine struck the friend in the head with his gun, Coppola said. 

Investigators believe Antoine acted alone, Coppola said.

Antoine was accompanied by his attorney, Tommy Damico, when he surrendered Tuesday. A warrant for Antoine's arrest was issued Saturday after the shooting. 

Damico said Antoine "has no reason to run from the authorities" and probably waited to turn himself in so he could pull together funds for a lawyer. 

"I think he's got a strong defense," Damico said.

As officials walked Antoine to a vehicle to take him to Parish Prison on Tuesday, Antoine told reporters he had nothing to say about the accusations.

Maxie's mother, Wanda Young, said the couple recently broke up after about a year of dating, and she knew of multiple incidents of domestic abuse. Maxie was a mother of two, her family said.

Niette Maxie said she hopes Antione stays behind bars because their family and friends had just spent a fearful last four days while police were looking for him. 

"The investigators diligently working on this investigation — along with the community who stepped up and helped with the search for him was able to put enough pressure where he turned himself in to authorities," Coppola said. 

Antoine was accused of fatally shooting a 22-year-old man after a game of dice in 1998, according to stories published in The Advocate.

Antoine was neither indicted nor cleared on that second-degree murder charge after a grand jury hearing. However, a month later, he was convicted of attempted possession with intent to distribute cocaine and sentenced to 15 years, newspaper records show. He served about seven years, said Ken Pastorick, a spokesman for the state Department of Corrections.

Niette Maxie said the victim in that case was one of her classmates from Central High School.

Antoine will be booked into Parish Prison on counts of second-degree murder, aggravated battery, illegal use of a weapon and aggravated assault, Coppola said.
