YOUNGSTOWN, Ohio - Investigators say Youngstown's latest murder victim was stabbed more than sixty times by a man with whom she shared a home.

Those revelations came Friday as 51-year-old David Hackett was arraigned on charges that he murdered 30-year-old Collena Lynn Carpenter, originally of Homeworth in Columbiana County.

Investigators revealed that Carpenter was staying with Hackett and his fiancee in Youngstown.

Police found Carpenter's body on a vacant lot on West Avenue early Monday. She had been stabbed more than sixty times. Police are being tight-lipped about a motive.

"When Mr. Hackets name came to light, we looked at his background and we saw that he had a very violent back ground," said Lt. Doug Bobovnyik.

21 News has also learned that Hackett was out on parole from a life sentence for a previous murder.

In 2009, Hackett was paroled from the Lorain Correctional Institution, where he had been serving a life term for a 1979 robbery and murder of a store owner.

According to sources, Hackett has also been charged with rape 3 times since his release, but has been found not guilty on those charges.

Friday, a judge set Hackett's bond at $2 million dollars.
