Hero Down: Mangham Police Officer Marshall Waters Murdered By Gunman

Alexandria, LA – Mangham Police Department (MPD) Officer Marshall Waters died in the line of duty on Thursday, nearly three weeks after he was shot during a traffic stop.

The attack occurred after the 49-year-old officer stopped a vehicle on Louisiana Highway 425 near the Richland-Franklin Parish line at approximately 1 p.m. on Oct. 17, KATC reported.

As Officer Waters stepped out of his patrol vehicle, the driver of the vehicle he had pulled over opened fire, shooting him in the lower abdomen beneath his ballistic vest, police said.

The alleged gunman, later identified as 27-year-old Hermandus Semien, fled southbound from the scene and into Franklin Parish, the MPD said in a Facebook post.

Officer Waters was rushed to Franklin Medical Center, and was later airlifted to Rapides Regional Medical Center in Alexandria in critical condition.

“Marshall is undergoing emergency surgery to control a vascular hemorrhage,” the Northeast Louisiana Ambulance Service (NLAS) said in a Facebook update later that night. “He has suffered life-threatening injuries. His condition is extremely critical.”

While Officer Waters was fighting for his life, the Franklin Parish Sheriff’s Office (FPSO) received a call of a crash on Louisiana Highway 562 near Fort Necessity at approximately 2:30 p.m. involving a vehicle that matched the description of the car that fled the scene of the shooting, according to the MPD.

Deputies responded to the scene and took Semien into custody without further incident, KATC reported.

According to police, the gunman was still armed at the time of his arrest, the News Star reported.

The Louisiana State Police said he has been charged with armed robbery, attempted first-degree murder of a police officer, and theft of a motor vehicle.

Semien has also been accused of robbing a Ville Platte pharmacy in September while dressed as a chipmunk, KATC reported.

Officer Waters underwent at least five emergency surgeries as he fought for his life, the MPD said in a series of updates on Facebook.

He remained hospitalized until his death on Thursday.

“It’s with great sadness and broken hearts that I, Chief Perry Fleming, and the Mangham Police Department have to inform you of the passing of Officer Marshall Waters PD3 who was shot in the line of duty on October 17, 2020,” the MPD chief wrote on the department’s Facebook page. “We ask that you please continue to pray for Marshall Waters family and the Mangham Police Department family during this time. RIP PD3.”

In addition to working part-time for MPD, Officer Waters also served as a full-time emergency medical technician with NLAS, KATC reported.

“He is an individual who spends most, if not all, of his time dedicated to public service and public safety,” NLAS spokesperson Shane Scott told the news outlet shortly after the shooting.

Our thoughts and prayers are with the family of Mangham Police Department Officer Marshall Waters, both blood and blue. Thank you for your service.

Officer Marshall Waters, your life mattered.
