DEXTER -- The Stoddard County Major Case Squad continues to investigate the death of a man who was found dead inside his Dexter home.
Although what caused the death of Jimmy Lynn Casey is not being released at this time, "we are for sure this is a homicide," said Stoddard County Coroner Kenny Pope. "We do know that for a fact."
Dexter Chief of Police Trevor Pulley agreed.
"We are investigating it as a homicide," he said.
Authorities learned of the 66-year-old's death at about 8 a.m. Thursday when Casey's home-health nurse called 911, Pulley said.
Casey, according to earlier reports, was found dead inside his mobile home in the 1100 block of Mulberry Street. He reportedly lived there alone.
"As soon as we were on the scene, detectives contacted headquarters, and I made the decision to activate the major case squad," Pulley explained.
Officers from every law enforcement agency in Stoddard County, as well as the Missouri State Highway Patrol, responded to assist in the investigation.
Officers, Pulley said, have been "actively investigating the case since Thursday."
Further details of that investigation are not being released at this time.
The major case squad, Pulley said, is activated for three days, but "I can request it be extended once the three days are up."
According the highway patrol's sex offender registry, Casey was a compliant sex offender at the time of his death.
A Casenet search revealed Casey pleaded guilty in May 2003 to the Class C felony of second-degree statutory sodomy in Stoddard County.
At that time, he was sentenced to five years in the Missouri Department of Corrections.
Casey reportedly pleaded guilty in connection with an offense involving a 16-year-old male in January 2003 in Bloomfield. Casey was 50 at the time of his offense.
Anyone with information regarding Casey or his death is asked to call Dexter Capt. Hank Trout or Lt. Cory Mills at 573-624-5512.
