CHICORA, Pa. (EYT) — Butler County law enforcement officials may be well on their way to solving the murder of an Armstrong County man.

According to a published article on ButlerEagle.com, Butler County District Attorney Richard Goldinger said two persons of interest in the murder of Gregory W. Bosko, 55, of Kittanning, have been behind bars for more than a week on outstanding warrants after they were found in Bosko’s car on March 24.

Bosko was reported missing on March 20. Four days later, Butler Police were called to West Wayne Street where Bosko’s car was parked with the people inside it possibly involved in drug use. Three people were found inside the car, including Joshua K. Greaves, 34, of Mercer, and Tiffany N. Hilliard, 30, of Butler.

According to online court documents, they were both charged for giving police false names.

Greaves was also charged with possession of heroin.

Unable to post $2,500.00 bail, he was lodged in the Butler County Jail.

Bail was set at $4,000.00 for Hilliard on two cases, and she remains lodged in the Butler County Jail.

Both individuals face preliminary hearings on April 10.

According to state police, Bosko was found with his neck slashed in a wooded area in Concord Township, Butler County, on Saturday, April 1.

According to Goldinger, a second woman in the car, is not facing charges.

Greaves has been in trouble with the law for more than a decade in several counties with convictions for theft, receiving stolen property, and DUI.

Hilliard has had convictions for receiving stolen property, theft, and drug possession.

Bosko has a criminal record dating back to 1991. Charges involve drug use and possession, receiving stolen property, shoplifting, bad checks, and theft; however, he hadn’t had any run-ins with the law for several years, other than a DUI charge in September of 2016.
