A Shreveport police officer and his K-9 dog were honored Tuesday by both his department and the Panola County Sheriff’s Office for arresting the man accused of fatally shooting Deputy Chris Dickerson.

Corporal LaBrian Marsden and K-9 Casper were given a commendation from Shreveport Police and a certificate of appreciation from the Panola County Sheriff’s Office for the arrest of Gregory Newson on Jan. 31.

“I can’t express the relief that came to all of the officers even during a time of grieving to know that the suspect that murdered our officer was in custody,” Panola County Sheriff Kevin Lake said during the brief ceremony.

Newson is accused of shooting Dickerson during a traffic stop in Gary on Jan. 31. Officials said he stepped out of the car and shot Dickerson six times. Dickerson was able to fire back at Newson, but Newson fled the scene. Neighbors living in the area radioed in Dickerson’s injuries, and a description of the car was shared with area law enforcement.

Officials said Marsden volunteered to monitor Interstate 20 for the car and spotted it, confirming the license plate and vehicle description with communications officers. When Marsden tried to pull the car over, officials said Newson would not stop. Newson’s car eventually crashed on Buncombe Road near 3132 and Hollywood Avenue in Shreveport.

Newson fled the car on foot, officials said, and Marsden deployed his K-9 Casper, who found Newson hiding in brush and grass. Casper bit Newson, and officers were able to take him into custody.

Lake called Marsden’s actions a “selfless act of bravery in apprehending an armed suspect.”
