A Marysville man was charged with a felony count of engaging in a pattern of corrupt activity April 4 after he allegedly sold heroin to informants working with the Union County Multi Agency Drug Enforcement Task Force.
The charge against Michael P. Ropp, 31, 13763 U.S. Route 36, Marysville, is a first-degree felony.
According to a release from the Union County Sheriff's Office, he was arrested after "a lengthy task-force investigation" during which he allegedly sold heroin to the informants five times from February through April this year.
All the sales took place in Marysville and one was made within 100 feet of a child, the release said.
Task Force investigators said Ropp is accused of buying large quantities of heroin in Columbus from a Mexican supply source, then repackaging it into smaller amounts before selling it.
According to the task force, Ropp allegedly supplied heroin to at least three people who later overdosed and had to receive "life-saving intervention" at a medical facility.
A fourth person who was found dead in Ropp's home died from an acute heroin overdose, according to a report from the Union County Coroner's Office.
The MADE Task Force did not identify any of the victims.
Union County Prosecutor David W. Phillips called Ropp's arrest "another major step forward in the fight against drug trafficking in our community."
The investigation is continuing; authorities said additional charges are expected to be filed with a Union County grand jury.
Agents from the federal Drug Enforcement Administration and troopers from the Ohio State Highway patrol assisted with the investigation.
The public is encouraged to report drug or suspicious activity to local law enforcement agencies. Information can be shared via the Crime Tip Line at 937-642-7653.
