There were at least three cases of violence against police over this last weekend. The worst was the shooting of Louisiana state trooper Steven Vincent, who has now died of his terrible injuries.

The Louisiana State Police posted an update to their Facebook page.

The suspect, Kevin Daigle, is in custody thanks to good Samaritans who came to Trooper Vincent’s aid.

Authorities plan to charge the accused shooter with first-degree murder after the death of Senior Trooper Steven Vincent, 43. Vincent had been trying to help a man whose pickup truck was stuck sideways in a ditch, Col. Mike Edmonson said.

“This loss exacts an enormous emotional toll on the state police family, but we will do what is necessary and proper to honor Steve and support those who knew and loved him,” Edmonson said in a statement Monday morning.

Edmonson said Kevin Daigle, 54, of Lake Charles, was under arrest at a hospital where he was taken after other motorists saw the fallen policeman and wrestled Daigle to the ground.
