Three state highway workers found a tire filled with about $100,000 in cash while picking up trash along Interstate 70 east of Indianapolis Friday, The Indianapolis Star reported.
Police told the Star the workers found the tire, which appeared to be from a large truck, in a ditch. When they picked it up, the tire fell apart and revealed the money, which was in denominations ranging from $5 to $100.
The workers then called the police, according to the Star.
Indiana State Police spokesman Mike Burns said the police suspect the money is drug money. Drug-sniffing dogs smelled drugs on the money, he said.
State police are not sure how long the tire was in the ditch.
