Story highlights Jeremy Mardis, 6, shot to death while buckled into front seat of vehicle, authorities say

Officers face second-degree murder and attempted second-degree murder charges

Shooting happened on a dead-end street at the end of a chase, coroner says

(CNN) Two police officers in Louisiana are facing murder charges after a 6-year-old boy was shot to death in the front seat of his father's vehicle, authorities said.

The shooting happened on a dead-end street at the end of a Tuesday night chase in Marksville, a town of about 5,500 about 90 miles northwest of Baton Rouge, authorities said.

It's unclear why officers pursued or why shots were fired, since investigators say there were no outstanding warrants against the father, Chris Few, and that no firearm was found in his vehicle.

Jeremy Mardis, a first-grader, was hit by five bullets in the head and chest as the officers pursued his father's car , according to CNN affiliate WAFB. His father was hospitalized with gunshot wounds and was listed in critical condition.

Officers Norris Greenhouse Jr. and Derrick Stafford are charged with second-degree murder.

"We took some of the body cam footage. I'm not gonna talk about it, but I'm gonna tell you this -- it is the most disturbing thing I've seen and I will leave it at that," State Police Col. Michael Edmonson said at a news conference late Friday. "That little boy was buckled into the front seat of that vehicle and that is how he died."
