Lowe says that during the course of an interview, investigators determined that the 35-year-old Noble had disposed of the rifle believed to have been used in the officer's killing. Police say he started acting suspicious when he saw the safe was damaged. Noble began to act "visibly upset and faked crying".
McCarthy has been charged with one count of first-degree murder in the shooting death of Gary Michael and with one count of armed criminal action, the Henry County prosecutor's office said Monday.
Police say Noble asked what type of weapon was used in the murder of Michael.
The Court has issued a warrant with a bond of $25,000 cash only.
As Michael exited his vehicle in downtown Clinton, the alleged shooter also got out of his auto and fired once at the officer before fleeing the scene and crashing his vehicle into an embankment about four blocks away, Lowe said. However, he then changed the story and admitted he bought the gun for McCarthy because he was asked to.
Noble allegedly pointed to the water and told police that's where he threw it. Police say they could see the stock of the weapon under the water.More news: Conte, Cahill Regret Sale Of Matic To Manchester United
Shooting suspect Ian McCarthy is being held at the Henry County Jail.
Shields claims Noble knew the weapon had been used in the crime.
The driver reported seeing McCarthy walking along a state highway near Bucksaw Marina, just east of Clinton, and he was arrested without incident late Tuesday, Lowe said.
"Noble said he panicked, told his wife he needed to take out the trash, took the gun and drove north of town", according to the affidavit. The detectives asked against and Noble allegedly said he did know where the gun was.
The Highway Patrol says Officer Michael had stopped a vehicle for a registration violation. He then went with officers to the intersection of NW 300th Road and NW 131st Road.
Investigators have said it's possible that other people helped McCarthy by giving him a ride or clothes.
