Dallas County Jail

DeSOTO, Texas — In an alleged retaliation killing, police in north Texas say a murder victim's brother shot and killed a man who had been mistakenly identified in several social media posts as a suspect.

The mistaken retaliation killing took place at a balloon release ceremony honoring the original murder victim.

On April 22, 2021, the DeSoto Police Department investigated a homicide in which 19-year-old Camran Kawshawn Collier of DeSoto, was shot and killed while sitting in the driver's seat of his Honda Accord in the 1100 block of Westlake Drive.

Days later, on April 25, 2021, friends and family had gathered at Les Zeiger Park, located at 401 Eagle Drive, in DeSoto, for a balloon release ceremony honoring Camran Collier.

"Immediately following the ceremony, one of the attendees, 20-year-old Lancaster resident Kolby Marquise Graham, was shot in the head by another participant in front of others who attended the ceremony," DeSoto police say.

Graham initially survived the shooting, was taken to an area hospital, but died several days later.

Police say none of the balloon release ceremony participants who witnessed the shooting came forward to provide information on the shooter to police.

Feeling a connection between the two shootings, DeSoto police continued to investigate that angle and determined Graham "had been mistakenly identified as Camran's killer on several social media postings," according to the department.

"22-year-old Norman Christopher Collier, IV, who is the brother of the murder victim Camran Collier, mistakenly believed the internet rumors about the identity of his brother's killer," stated DeSoto police. "Norman Collier then took revenge against the wrong man at his brother's balloon release ceremony by shooting Kolby Graham on April 25, 2021."

Norman Collier was arrested and charged with capital murder in connection with Graham's slaying. He has since been booked into the Dallas County Jail where he is being held on a $1 million bond.
