Unsolved case: Detectives from Marion are looking for information about the murder of a construction worker

More than a decade after the remains of a construction worker were found at Fort McCoy, the Marion County Sheriff's Office is asking for the public's help in bringing the killer to justice.

On August 18, 2014, a utility worker discovered human remains near the 19000 block of NE Highway 315, according to MCSO.

Investigators launched an investigation which revealed that the human remains belonged to Vitaliy Olenchuk. It was determined that he had been murdered, with the cause of death listed as “blunt force trauma.”

The sheriff's office said Olenchuk was born in Ukraine on December 9, 1972. When he came to the United States, he was seeking a new life and had ties to Eastern European communities in Jacksonville and St. Augustine.

Olenchuk was a construction worker, and his life was last confirmed on March 16, 2012. However, the MCSO stated that there was evidence that Olenchuk may have been seen in the Marion County area in July 2013.

“As we continue our investigation, we need your help to uncover the truth about Vitaliy's fate,” MCSO said in a social media post. “His family deserves closure and we are committed to bringing the person responsible for his death to justice.”
