Update (January 17, 2019): Three men have been arrested for the shooting death of Shreveport Police Department rookie Chateri Payne.

Treveon Anderson, 26, Lawrence Pierre, 22, and Glenn Frierson, 38, were taken into custody on Tuesday, reports CBS19. Anderson was Payne’s boyfriend and the father of her daughter.

The men were charged with second-degree murder, and their bonds were set at $500,000, according to The Shreveport Times. Shreveport Police Chief Ben Raymond said Anderson pulled the trigger and lied about her being shot by a stranger outside their home. Pierre helped the police recover the gun used to kill Payne. It is unclear if Pierre and Frierson were on the scene during the shooting.

Original: A Louisiana officer was killed before heading into work just two months after completing police academy training. According to NBC News, the mother of a young child was shot on Wednesday at 8:30 p.m. outside of a house before heading to work the night shift.

Police say the motive of the shooter was unclear. The officer, identified as Chateri Paye, was wearing her uniform when she was rushed to Ochsner LSU Health hospital where she died.

Gonzales Police Department officer Duane Carpenter tweeted a message about the officer who had just graduated from the academy in November after joining the Shreveport Police Department in July.

"Officer Chateri Alyse Payne, 22 years old, just recently became a police officer for the Shreveport Police Department in Louisiana. As she was on her way to work the night shift last night, Officer Payne was shot in the head and died at the hospital," Carpenter wrote

CBS News reported Payne posted a celebratory Facebook message when she finished training, noting the process of achieving her goal and dedicating herself to the work of protecting citizens.  

"Long days. Aching nights. But I decided to stand tall on my dream. Main lesson taught was to never lose sight of who you are and where you come from," Payne wrote.

"My personal mission is to become that positive influence. To protect those who can’t protect themselves and to at least try to push someone to being a better version of themselves," the 22-year-old continued.

Shreveport substitute Police Chief Ben Raymond reported when officers arrived on the scene after receiving the 911 call, Payne had been shot multiple times and was "fighting for her life." He could not conclude whether the shooting was due to a domestic dispute but said the department is "not willing to rule out anything."

"Every life is precious, and the taking of any human life is unacceptable," Raymond told CBS. "But when a servant who has taken an oath and committed their life to protecting others is violently taken from us, we all collectively feel the pain of that loss."
