CRANFORD - Police are continuing their search inside Liberty State Park for the body of a Cranford woman who was murdered by her ex-boyfriend earlier this week, according to police.

Matthew Ballister was arrested for the alleged killing of April Wyckoff, but will not tell investigators where her body is.

Police say they have evidence Ballister was in Liberty State Park in Hudson County sometime between Tuesday and Wednesday. Investigators believe that Ballister beat Wyckoff to death inside his Union Township home.

Police have been looking for Wyckoff in remote areas of the park as well as locations in Union and Essex counties.

Police say Ballister’s mother has also been jailed for allegedly working as an accomplice.
