But police say his attack on his daughter and wife happened about a mile away at the alleged killer’s home, all of it stunning neighbors.

“I couldn’t sleep at all last night,” neighbor Kara Morley said. “I was up all night.”

Kelemen had been sought by the U.S. Marshals Service and local authorities after he allegedly struck his 22-year-old daughter, Katherine Kelemen, with a bat multiple times, resulting in her death. He was facing a first-degree murder charge.

The photo below is from Facebook and was confirmed by neighbors to be Katherine Kelemen. Neighbors tell CBS3 she was a senior at Temple University and was set to graduate in May.

Gregory Kelemen was also facing attempted murder for allegedly attacking his wife. Police say he struck his wife, Sheri Kelemen, with the baseball ball multiple times, leaving her in critical condition.

Court papers show she was sleeping and was “awakened by her husband Gregory Kelemen, when he began striking her with the baseball bat,” adding during that assault her husband was saying, “I can’t take it anymore.”

Both victims were found by Voorhees Township Police inside their home on the 100 block of Round Hill Road, just before 7 a.m. Monday after receiving a 911 call from the home. Police say both were suffering from injuries associated with blunt force trauma.

Katherine Kelemen was taken to a local hospital, where she was pronounced dead.

Sheri Kelemen is currently listed as critical but stable according to the hospital where she is being treated.

“Beyond sickening, that’s for sure,” neighbor Nick Bennett said. “Something you would never expect. Such a nice family, looked like they were always doing things together, going on a walk, doing groceries, things like that.”

Police are still investigating and haven’t said exactly what lead up to the deadly baseball bat attack.
