The shooting death of six-year-old Jeremy David Mardis in Marksville, Louisiana made him the youngest civilian killed by police so far this year. Now, two officers are facing murder charges.

BuzzFeed reports that Derrick Stafford and Norris Greenhouse were taken into custody on Friday after allegedly shooting at the vehicle at “the conclusion of a pursuit.” Stafford, 32, is a member of the Marksville Police Department and Greenhouse, 23, works for the Alexandria City Marshal. At the time of the incident, both were working part-time for another agency.

Mardis died at the scene on Tuesday after being struck by bullets in the head and chest. His father, Chris Few, was also hurt and remains in critical condition. Col. Micheal Edmonson reviewed the body camera footage from the shooting and said “it was the most disturbing thing I have ever seen.”

The officers maintain that they were attempting to serve a warrant but Edmonson told The Advocate that “no warrant has materialized.” Few was reportedly unarmed when police fired at least 18 shots at his vehicle. Louisiana State Police is currently investigating the situation.
