POINTE COUPEE PARISH, LA (WAFB) - A deputy with the West Baton Rouge Sheriff's Office was killed in a double murder-suicide in Pointe Coupee Parish on Tuesday.

Pointe Coupee Parish Sheriff Bud Torres said Deputy Donna Leblanc of WBRSO and her 21-year-old daughter, Carli Jo, were killed in the shooting. Officials identified the suspected shooter as Gregory Phillips. Torres added Leblanc was the wife of Mark Whitmore, a trooper with Louisiana State Police.

A number of investigators from several agencies were called to the scene of the shooting at a home in the 14400 block of LA 416 in Glynn, Louisiana around 4 p.m.

West Baton Rouge Parish Sheriff Mike Cazes said Leblanc is the first deputy he has ever lost. She had been with the sheriff's office for 22 years.

"I just saw her yesterday," Cazes said. "Today's her day off. She's gone now."

"She was a veteran officer," Torres said of Leblanc. "She was one of the first female deputies to work in West Baton Rouge Parish on the road. She was, in my opinion, an outstanding officer and a great human being."

Investigators said Phillips was an estranged neighbor who lived across the street. The sheriff's office reported Phillips approached Leblanc at her carport and "shortly thereafter a gunfight erupted," according to Torres.

"Ms. Leblanc was able to get three rounds off of her pistol and there were multiple rounds shot by Mr. Phillips," Torres stated.

The sheriff added Phillips eventually shot and killed Leblanc before turning to shoot her daughter, who was standing on the porch. According to Torres, Phillips then shot and killed himself.

Investigators said Leblanc's 9-year-old daughter was inside the home at the time and was able to call for help.

Assistant District Attorney Tony Clayton said there are security cameras on the suspected shooter's home and at least one was pointed directly at the victim's home. However, Sheriff Bud Torres said Wednesday morning that the cameras at Phillips' home pointed at Leblanc's mobile home were not working.

Torres said there had been "some difficulty between the neighbors," but deputies do not have a motive for the shooting at this time.

"We don't know exactly the extent of [a previous conflict], but I know there was not a pleasant relationship between the neighbors. There was an ongoing contact with them and it wasn't pleasant," Torres explained.

The Pointe Coupee Parish Sheriff's Office will lead the investigation, with the assistance of Louisiana State Police and the West Baton Rouge Parish Sheriff's Office.

"We'll give all the resources we've got to the sheriff here," said Col. Mike Edmonson, superintendent of Louisiana State Police. "My heart is with Sheriff Cazes and his deputy. Of course, the situation here is a horrible situation that you don't want to see. We're going to be there with our trooper, the husband and just counsel him through this. Just a horrible, horrible situation and you just don't expect things like this to occur, but they did, we have to deal with it, get through it and find out exactly what happened and we certainly will."

Anyone who knows anything about the incident is asked to call the Pointe Coupee Sheriff's Office.
