The man accused of a savage June 7, 2012, attack on a Sharon woman that left her dead pleaded guilty Monday to third-degree murder charges.
Anthony Argenziano, 21, will be sentenced Aug. 30 by Mercer County Common Pleas Court President Judge Thomas R. Dobson.
He could face between 20 and 40 years in state prison, according to a news release issued by District Attorney Robert G. Kochems.
Because of the plea, prosecutors will withdraw first-degree murder charges against Argenziano for killing Tracey Lynn Goga in her East State Street apartment.
That charge “requires proof of the specific intent to kill and that intent may be negated by proof of voluntary impairment,” Kochems said.
Argenziano told authorities he blacked out the night of the stabbing after taking prescription pills.
He stabbed Goga more than 30 times in the neck and torso inside her apartment that night. He was arrested June 9, 2012, at a Youngstown bus station, where he had a one-way ticket to New York.
Argenziano told authorities he’d been watching movies with a friend before the attack that night and had taken 10 1-milligram Xanax pills that day. Xanax is an anti-anxiety medication.
“The commonwealth will have no further comment on this matter until sentence court,” Kochems said in a news release.
