A Butler County judge set a $5 million bond for Dominick Grubb, who prosecutors said tried to hire someone to kill a female witness.

Between Christmas Eve and Jan. 3, Grubb, 18, of Hamilton, allegedly tried to hire a jail inmate to kill a woman, according to Wednesday’s grand jury indictment. According to prosecutors, the woman was a witness involved in Grubb’s other criminal case that resulted in him being incarcerated.

In December, Grubb was charged with aggravated robbery and has been in the Butler County Jail ever since. He’s now charged with conspiracy to commit murder, and waived his right to have the indictment read in open court.

The inmate was facing an aggravated burglary charge and prosecutors say he allegedly offered another inmate, who was a confidential informant, an initial payment of $100 via his jail commissary account and a gun, then would pay an additional $2,500 to kill the witness.

Court records said Grubb met with the informant to provide details about the victim, including social media accounts, address, the type of car, and family information, down to the bus stop of the victim’s child. Prosecutors said he “did not care if the intended victim’s child was also killed during the shooting.”

Court documents showed Grubb engaged his mother to deposit the $100 initial payment in the informant’s commissary account, which authorities said she did.

The intended victim’s identity was redacted from the indictment.

Before Butler County Common Pleas Judge Jennifer McElfresh set the $5 million bond, Assistant Prosecuting Attorney Jon Marshall said, “The indictment speaks for itself.”

“The allegations involved and the defendant’s stated desire to murder a witness is very serious on its own,” he said, adding he requested bond be set “in an amount that’s commensurate with the seriousness of the charge.”

Court records also showed Grubb told the informant how he wanted the murder to be carried out, and if that person “would not carry out the murder of his intended victim, the defendant would find someone else.”

Grubb has been in the Butler County Jail in Hamilton since Dec. 13 related to the aggravated burglary charge, a first-degree felony, with a firearm specification. He had already in the Butler County jail since December on a $100,000 bond.

Should the bond be posted, Grubb would be required to wear a GPS monitor and have no contact with the victim.

Both cases will be heard at 1 p.m. April 3 for a plea or trial setting.
