CLARKSDALE, Miss. — Mississippi authorities have taken two suspects into custody in a shooting that critically injured a Clarksdale police officer.

Investigators said the father of one of the suspects turned him into police, but they have not released either suspect’s name so far.

Meanwhile, Cpl. Derrick Couch remains at Regional Medical Center here in Memphis.

City leaders said investigators were able to track the suspects’ every move, largely because of security cameras that police said caught the shooting.

The security camera video shows two men slowly making their way into the Corner Grocery across from the Clarksdale City Hall. City leaders said those are the men who robbed the store and then took off running across the parking lot and down the alley.

“We put a saturation of unit looking for anyone who fit the description,” Clarksdale Mayor Bill Luckett said.

Luckett said Couch saw the larger suspect — the one seen limping in the video — and tried to stop him behind a nearby church. Luckett said that man with the limp shot the officer, the bullet going through his eye socket into his head.

“I actually saw video of the officer being shot, it’s grainy and long distance, but it’s obvious what happened,” Luckett said.

Security cameras at the store and in the alley and even the mayor’s law firm helped investigators build their case against the shooter. The suspected shooter’s father saw it and turned him in to police.

So many who know the officer are prayers he pulls through and grateful the video was there.

“I been knowing him, been knowing him for years,” said Mary Morgan, one of Couch’s friends.

“It’s sad that a man trying to do his job and he gets shot,” said Ralph Jackson, who also knows Couch. “It was a lucky shot; I don’t think they were aiming, and they just turned and shot.”

Obviously investigators aren’t showing all that video footage, but they’re certainly using it to help them solve the case.
