Authorities in Louisiana captured 27-year-old Grover Cannon Thursday afternoon. Cannon was wanted for the fatal shooting of a Shreveport police officer Wednesday night, but when the shooting occurred, Cannon was already wanted on a separate, unrelated murder charge.

Cannon was found after a day-long search, around 3 p.m., hiding in a garage structure at a Shreveport home, about a mile from where the officer was killed. Authorities searched the area following a tip from the resident, CBS reported. U.S. Marshals warned residents not to engage or approach Cannon, who was considered armed and dangerous.

According to Shreveport Police Chief Willie Shaw, Officer Thomas LaValley, 24, was responding to a call about a possible intruder in a home threatening to harm the people inside Wednesday when he came in contact with Cannon. Unbeknown to LaValley, Cannon was armed, and as LaValley entered the home, Cannon shot him multiple times.

LaValley, who had been with the force for four years, was transported to the hospital where he was pronounced dead.

Cannon fled the scene and sparked a massive manhunt, with the FBI offering up to $25,000 for information leading to his arrest.

“No matter what rock he crawls under we will find him,” Shaw said. “I would suggest that he turn himself in immediately. Because we are looking for him. I say ‘we’ in the biggest sense of the word. We are not bound by state lines. We are not bound by county lines. We are not bound by country lines… We will not rest until this individual is brought to justice.”

The FBI, the Shreveport Police Department, the U.S. Marshals Service, Caddo Parish Sheriff’s Office and Louisiana State Police all played a part in Cannon’s capture.

Before LaValley was killed, a warrant was already issued for Cannon, who was charged with second-degree murder for the shooting death of a man on July 15. The second-degree murder charge would automatically garner a life sentence for Cannon, but with the first-degree murder charge he now faces for killing LaValley, Cannon is looking at the possibility of the death penalty.
