Three Delaware residents were indicted on aggravated robbery charges Wednesday by a Delaware County grand jury in connection with an April incident.

Derek James Hill, 26; Phillip A. Williams, 49; and Cara Judith Grimes, 23, all Delaware residents, were indicted Wednesday afternoon. Each faces one charge of aggravated robbery, a first-degree felony.

The charges carry specifications that a firearm was used to commit the offense. The Ohio Revised Code states that the specification would add three years to a potential prison term.

No arraignment dates for the trio had been scheduled Thursday afternoon.

Delaware police report on April 15 that Spenser Cramer, 22, of Delaware, came to the lobby of the police department and reported that he had given a ride to a woman he knows, Grimes, and two men he didn’t know, Hill and Williams.

Cramer said that during the ride the men threatened to seriously harm or shoot him and robbed him of several items he had in his car. Police report the items were $1,500 in Hollywood Casino chips, a cellphone worth $200, a Nintendo 3DS worth $335 and headphones worth $250, as well as $500 in cash.

Police said Cramer was unharmed after the incident.

Police served a search warrant and took the trio into custody when they found several of the items in the home of one of the suspects.

The trio appeared in Delaware Municipal Court where bail was set at $250,000 for Hill and Williams by Municipal Judge Marianne Hemmeter. Hemmeter also set a $100,000 bond was set for Grimes.

They all were in the Delaware County Jail Thursday, awaiting their arraignments in Delaware County Common Pleas Court.

Common Pleas Judge Everett Krueger will preside over the case.
