EDISON - New court documents released in the murder case of a New Jersey woman show that her final moments were likely filled with sheer terror and the knowledge of certain death at the hands of her boyfriend, Matthew Ballister.

Court filings in the case of April Wyckoff include information on some of the evidence investigators have gathered on her alleged killer.

Matthew Ballister has been charged with felony murder, kidnapping and desecration of human remains.

The latest criminal complaint alleges Ballister attacked Wyckoff inside her car, threatening and terrorizing her before taking her life on Oct. 22.

The filings also allege Ballister held Wyckoff against her will, leading to the additional charges of kidnapping and criminal restraint.

The prosecutor's office will not say where Wyckoff's car was parked when Ballister allegedly threatened and assaulted her, but authorities found Wyckoff's car abandoned in Newark some time after her murder, with the engine running and the driver's door open.

Some of Wyckoff's dismembered remains were later recovered in Newark.

The complaint also reveals some of the evidence investigators have to work with including witness statements, police surveillance, evidence seized from Ballister's home and car, his mother Eleanor Schofield's car and Wyckoff's car.

There is also a 911 call and surveillance video from from multiple locations.

Schofield is charged with hindering the investigation. Schofield and Ballister have pleaded not guilty. Ballister is being held on $5.5 million bail.
