Krystle Sue Weaver’s trial on charges she stabbed a Greene Township man to death in an attack last year in Greenville that left his daughter critically wounded is set to begin May 11.

Ms. Weaver, 21, Fowler, Ohio, is accused of stabbing Thomas Lorigan, 44, of 183 Ray Road, Greene Township, and Heather Turk, 22, on May 20 in Ms. Turk’s former apartment at 94 Clinton St.

The trial date was set Tuesday during a meeting between Mercer County District Attorney Robert G. Kochems, Ms. Weaver’s attorney Stephen Misko of Butler, and county Judge John C. Reed.

According to police, Ms. Weaver and her boyfriend, Ronald Victor Machado, 21, Jamestown entered Ms. Turk’s apartment and waited in the dark for her to come home. When she did, accompanied by her father, police say Ms. Weaver and Machado attacked Ms. Turk and Lorigan, stabbing them repeatedly.

Ms. Weaver claims Machado was the only one who stabbed anyone.

Machado hanged himself May 24 in his cell at Trumbull County Jail, Warren, while awaiting extradition to Mercer County.

Authorities have not disclosed a motive for the crime but the couple had once lived with Ms. Turk in her apartment.

A pre-trial conference was scheduled for May 7 in Reed’s chambers, when prosecutors and Misko will review evidence in the case, Kochems said.

Ms. Weaver is charged with homicide, attempted homicide, conspiracy to commit homicide, aggravated assault, burglary and two counts of robbery.

Ms. Turk was released from the hospital in December and is recovering with relatives while she undergoes physical and speech therapy.

Her two young daughters were with her and Lorigan when the attack happened, but the girls were not harmed.

Ms. Turk’s mother Brenda Agbley, Forest Hills, Pa., had been helping care for her and the girls until tragedy struck the family again.

Mrs. Agbley, 40, was strangled Jan. 23 in her home by her husband, Jude Agbley, 34, police have said.

Agbley, a Ghanian national who married the former Greenville woman in August, is facing a homicide trial in Allegheny County, where he’s being held without bond.
