Authorities say the brother on brother murder Thanksgiving evening in Jefferson Parish left a St. John Parish Sheriff's deputy dead.
"It is with deep sadness that St. John the Baptist Parish Sheriff Mike Tregre and the men and women of the St. John Parish Sheriff’s Office announce the passing of our colleague and friend, Deputy Shaquille Guerin who was tragically killed in Jefferson Parish," the St. John Sheriff's Office posted.
Officials say Guerin had been with the St. John Parish Sheriff’s Office for eight years.
“Shaquille did his job well! He had the heart of a public servant,” Sheriff Tregre said. “He carried and showed positivity as an employee for the St. John Sheriff’s Office and teammate to his coworkers.”
Guerin was assigned to the uniform patrol division and worked in the detective bureau.
"Deputy Guerin is survived by his wife Roxanne and their three children. We asked that you would keep his family in your thoughts and prayers."
The Jefferson Parish Sheriff’s Office is investigating the homicide in Waggaman.
JPSO Captain Jason Rivarde said, "One adult male was shot and killed, and his brother has been arrested for second degree murder."
It happened just after 5:30pm Thursday.
"Deputies were called to the 30 block of Marigold Lane in reference to a shooting. Upon arriving, they observed the victim lying in the street in front of a residence."
Rivarde says deputies and EMTs tried to save the Guerin's life, but could not.
"The victim was pronounced dead at the scene."
Investigators say the deputy's brother drove off after killing him.
"Deputies were able to develop a suspect vehicle used by the brother to flee the scene, and that information was spread across the local area. Around 7:00 pm, a deputy spotted the vehicle near the intersection of Ames and Lapalco Boulevards. When deputies attempted to stop the suspect, he refused to stop."
Cops chased the suspect into Jean Lafitte, where he stopped in the 100 block of Jean Lafitte Blvd.
"The suspect ran from the vehicle, and deputies were able to catch him and take him into custody. After searching the area, deputies were able to locate a firearm along the suspect’s path as he ran from deputies."
