SPRINGFIELD — Two Springfield residents have been charged in the death of a man whose body was found in Greene County in June.

Randall E. Smith, 43, has been charged with murder, tampering with evidence and abuse of a corpse in the death of Curtis Gene Miller. Jody Apone, 36, was charged with abuse of a corpse and tampering with evidence.

Apone was Miller’s girlfriend and lived with him at a home on Oak Street. Smith is Apone’s brother, said Springfield police Chief Steve Moody.

According to officers, sometime between May 26 and June 10, Smith argued with Miller at 119 N. Jackson St. Smith then “struck (Miller) about the head and body repeatedly, causing injuries that resulted in death,” a police report stated.

After Miller’s death, Smith and Apone allegedly wrapped the body in a tarp and drove it to Gravel Pit Road in Cedarville, where they dumped it in a flooded quarry. Several days later, the pair came back to the garage and tried to clean up the crime scene to hide any evidence, police said.

Miller’s body was found by Greene County Sheriff’s Office deputies on June 10.

A Montgomery County coroner ruled Miller’s death a homicide by unspecified trauma.

Moody wouldn’t discuss what may have motivated Smith to kill Miller, but said “good detective work” by his detectives and those in the Greene County Sheriff’s Office led them to their suspects.

“This has been a ‘who done it’ from the start,” Moody said.

“Once detectives from Greene County established that Mr. Miller resided here, you’ve got to go back to where people live and talk to people who knew them,” Moody said. “Certainly, Jody Apone was one of the first people we interviewed because they had a relationship.”

Last month, Apone told WHIO-TV News Center 7 she and Miller argued Memorial Day weekend, and that was the last time she’d heard from him.

“When Curtis didn’t want to say things, he would leave,” Apone said. “And he would leave for periods of time before. The week was the longest. A couple of days he would go camp, and I figured that’s what it was.”

Apone and Smith were arrested Monday without incident in Springfield. Both pleaded not guilty to the charges during an arraignment in Clark County Municipal Court on Tuesday.

Bond was set at $50,000 for Apone and $500,000 for Smith, according to court records.

Both cases are expected to be presented to a Clark County grand jury in the coming weeks, Moody said.
