MINER, MO (KFVS) - The son of a man and woman who were found dead in the Mississippi River was back in court on Thursday, January 14.
Thomas Wayne McRoy, 37, was charged with two counts of first degree murder and two counts of armed criminal action.
On Thursday, he entered a not guilty plea and waived his formal arraignment.
His next appearance will be on Jan. 28 at 1 p.m.
McRoy also waived the formal reading of his charges at an arraignment on Wednesday, November 25.
A preliminary hearing was set for December 23, 2015.
The family lived in Miner, Mo.
According to the probable cause statement, police went to the home and spoke with Thomas McRoy on Tuesday, who said his parents had left with friends and that he didn't know who they were.
Officers noticed a black Jeep that was backed up to the home.
Upon returning to the scene later, police found that Jeep was gone.
Police found blood on the door and in the bed of a white pickup truck that was there, which belonged to Larry McRoy.
Also in the back of the truck was a loaded 12 gauge shotgun.
The bodies of his parents were later found in the Mississippi River.
"At that time, we had got information from KFVS12 of a body found that washed up in Dorena," Chief Griggs said. "We sent some investigators over there and the confirmation was soon made after that, it was Larry McRoy."
On Tuesday evening, a Missouri State Highway Patrol trooper recognized the suspect's vehicle in Carter County, pulled it over and took the suspect into custody.
McRoy allegedly admitted during the traffic stop that he had shot both of his parents with a .22 rifle in the living room.
A search of the home revealed a large amount of blood, a bone fragment, and a bullet fragment.
Mississippi County Coroner Terry A. Parker says autopsies for Larry and Roxann McRoy found both died from gunshot wounds. Their visitation was Nov. 22 and the funeral service was Nov. 23 at 11 a.m.
McRoy is being held at the Scott County Jail. His bond is set at $200,000 cash only.
Authorities say McRoy has been cooperating with police during the investigation.
Chief Griggs wanted to thank the following departments for their help in the investigation: the Major Case Squad, Mississippi County Sheriff's Office, Scott County Sheriff's Office, Missouri State Highway Patrol and the Sikeston Police Department.
