From time to time, Kye Boudreaux would bring a friend as he went fishing.

On Wednesday, the avid fisherman let Detrell Scott come with him.

And that, authorities said, was a fatal error.

When Boudreaux’s boat was spotted around 5:30 a.m. drifting in the waters of the Intercoastal Waterway near the Jack Miller boat landing in Plaquemine, his family went to look for him.

His parents discovered his body at 8:30 a.m. at the family’s campsite near Grand River in Plaquemine. Boudreaux had been shot in the head, Iberville Parish Sheriff Brett Stassi said.

Eight hours later, Scott, 22, 24725 Damon St., Plaquemine, was arrested, having confessed to robbing and fatally shooting Boudreaux, Stassi said.

The sheriff said Scott told investigators that Boudreaux, 26, also of Plaquemine, had allowed him to tag along Wednesday morning as he fished along the Intercoastal Waterway.

“On occasion (Boudreaux) would bring a friend with him. He brought the wrong one today,” Stassi said Wednesday following Scott’s arrest. “When they got to the camp, Detrell Scott used the victim’s gun to take everything he had before he shot him.”

In addition to Boudreaux’s gun, Scott stole the victim’s wallet, car keys, cellphone and some drugs Boudreaux was carrying, Stassi said. The sheriff would not indicate the type of drugs or how much drugs and money were stolen.

“Then he used Boudreaux’s boat to escape the campsite, and then he used the dead guy’s truck to make an escape to his house,” Stassi said.

Detectives initially thought Boudreaux may have drowned after his empty boat was pulled ashore Wednesday morning.

Sheriff’s deputies found Boudreaux’s truck and trailer partially burned around 7:30 a.m. in a cane field off La. 1 behind the Relax Inn motel.

“Thank God (Scott) was unsuccessful in burning the vehicle,” Stassi said, “(but) we ended up with three different crime scenes. It’s horrendous.”

By 12:45 p.m. Wednesday, detectives had interviewed more than 25 people, seeking information about the crime, Stassi said. The Sheriff’s Office was assisted by officials from the state Department of Wildlife and Fisheries and the State Police.

Around 1 p.m., authorities returned to the Jack Miller boat landing after having gathered evidence from the scene at the family campsite.

A group of spectators claiming to be friends of the victim looked on as officials placed Boudreaux’s body into the back of a State Police vehicle to be taken to the crime lab for a full autopsy.

Boudreaux’s friends all declined to comment Wednesday. Repeated calls to his parents were unanswered.

The sheriff was visibly shaken. Stassi said the victim’s parents are close friends of his.

“I can only feel for the family,” he said. “This has been a roller coaster ride; then to end when they found the body. It really rings home, but we have to handle this the same way we handle any other case, no matter if I know the victim or not.”

The sheriff described Boudreaux as an “outdoors man” who liked fishing and horseback riding.

According to his Facebook profile, Boudreaux recently started working as a heavy-equipment operator at Summit Industrial Construction in Plaquemine. He previously worked at Dow Chemical.

Stassi said Boudreaux did not have any previous drug-related charges but he had been charged in Plaquemine with “a few misdemeanor” offenses in 2008.

Scott was last arrested in November 2012 and booked in Baton Rouge on a theft charge, a sheriff’s official said. The outcome of that case could not be immediately determined.

On Wednesday, around 4 p.m., Scott was booked into the Iberville Parish Jail on counts of armed robbery and first-degree murder.
