Race car driver Johnny T. Dowey faces cocaine distribution charges in state and federal courts, and a federal magistrate has imposed an additional $150,000 bond.

Last week, Dowey posted $50,000 in cash on a $500,000 bond after he was arrested on state charges. He was accused of trafficking in 9 ounces of cocaine, which investigators allege he sold to an undercover agent on three occasions.

Dowey, 43, was released from the Richland County Detention Center on Wednesday but was served with federal warrants Friday and reincarcerated at the jail.

The state and the federal governments have “concurrent jurisdiction” in drug-trafficking cases, but federal authorities declined yesterday to explain why they had Dowey arrested after his release on state bond last week.

U. S. Magistrate Cameron M. Currie told Dowey yesterday that he could secure the $150,000 federal bond with family property or pay a corporate surety company to secure the bond. But she said she would not allow him to post his own assets as collateral.

“I feel like a man is less likely to run if he knows his brother or sister would lose their house,” she said.

If Dowey elects to have a corporate surety, he must disclose the source used to pay the company’s fee, she said.

There is no requirement in state court to disclose the source of bail money.

Dowey estimated the value of his construction business, Carolina Wrecking and Hauling Co., at $250,000 with about $47,000 in outstanding debts.

The company has the contract to clean up the site of the old Wade Hampton Hotel, which was imploded last month.

One of the alleged drug transactions involved 1 ounce of cocaine and occured Sept. 6 at the hotel site at the corner of Main and Gervais streets, said Assistant U. S. Attorney Cameron B. Littlejohn.

Another sale involving 1 ounce of cocaine occurred Sept. 5 at Calhoun and Bull streets, Littlejohn said.

The third sale, in which only the state courts currently have jurisdiction, involved 7 ounces of cocaine and occured Sept. 10 in the woods of U. S. 321 north of Columbia, documents show.

Dowey said he is divesting himself or his interest in Blaney Drag Strip near Elgin, which he has leased for 10 years.
