Recording of testimony and legitimacy of warrants discussed in Bosko murder case

November 15, 2019 News Extra

Joshua K. Greaves, 36, has been in Butler County Prison since his arrest in March 2017 for the murder of Gregory W. Bosko, 55.

Prosecutors told a Butler judge Friday they worried a key witness in a murder case is at risk of dying from a heroin overdose, and that her testimony would be critical for an eventual trial.

“There were only three witnesses to this murder, one is dead,” Assistant District Attorney Ben Simon said.

The three people who witnessed the 2017 murder are: the victim, Gregory W. Bosko, 55, of Kittanning, whose throat was slashed; the alleged murderer, Joshua K. Greaves, 37, of Pittsburgh; and Tiffany Hilliard, 33, of Beaver Falls, Greaves' alleged co-conspirator who took a plea deal in exchange for her cooperation. Prosecutors allege that Greaves killed Bosko in March 2017 during a drug deal.

Friday's hearing was held to address a number of issues between prosecutors and Greaves' lawyer, Christopher Capozzi, including recording Hilliard's testimony, the constitutionality of the death penalty being pursued by prosecutors and the legitimacy of several warrants authorities executed to collect evidence against Greaves. Shaffer will make a decision later.

Capozzi also criticized prosecutors for cutting a deal with Hilliard.
