A man convicted in 1984 of abducting and raping a female Ohio University student was found guilty Wednesday of three counts of unlawful sexual conduct with a 15-year-old girl.

After two days of trial, the jury took little over an hour to convict Ronald “Ronnie” Clark, 43, Athens County Prosecutor C. David Warren said.

Athens Court of Common Pleas Judge L. Alan Goldsberry sentenced Clark to 12 years in prison in Lancaster — four years for each count of unlawful sexual conduct with a minor, Warren said.

“We were disappointed by the jury’s decision, and (Clark) plans to file an appeal,” Clark’s defense attorney, Van A. Gander, said.

Clark had a relationship with the 15-year-old high school student between February 16, 2006, and March 21, 2006, during which time the two had three sexual encounters, Warren said. At the time, Clark was on parole from the 1984 convictions, and he is currently in prison for a violation of that parole.

The case was not immediately reported. Warren said he attributes the delay to “typical teenage stuff. She was hanging out with an older fella, but the male should have known better. It is against the law.”Among the evidence against Clark, who entered a not guilty plea, were about 20 hours of cell phone conversations between the two, Warren said.

The jurors were not aware of Clark’s previous convictions — 1984 rape and abduction convictions and one in 2004 for felony drug possession — during the trial because Clark elected not to take the stand, Warren said.

“(Clark) showed no remorse for his actions,” he said.

Clark will be registered as a sex offender. He was not registered for his 1984 rape conviction because laws about registering sex offenders were not created until the mid-1990s, Warren said.
