Marcial Lopez, 40, was cited for a marked lanes violation and released but deputies kept his car and the money.
Deputies watched as a vehicle turned south on Ohio 4 from the turnpike at about 1 p.m. After the car veered off the road several times deputies stopped it. The driver, identified as Lopez, told deputies he was headed home from visiting a friend in Michigan.
Deputies called in Perkins police dog Uganda who smelled drugs in the car, though none were found.
“We still believe a nexus exists between the money and illegal activity,” Erie County Chief Deputy Jared Oliver said.
DEA agents were contacted to assist in the investigation.
