Transcripts from a probable cause statement obtained by WZZM-13 are showing more details into what investigators found inside of the home and vehicle of kidnapping suspect Jeffrey Willis.

Willis faces multiple charges in connection to an attempted abduction of a 16-year-old girl in Muskegon County back in April. Those charges include kidnapping, assault with a dangerous weapon, and two felony firearm charges.

Police found a mask, rubber gloves, photographs of females chained and bound, batting gloves, and a ball gag inside of locked boxes in his van. They also discovered a 22-caliber pistol with the serial number scratched off, and a bar with wrist restraints.

When investigators searched Willis' home, they found a thumb drive with child pornography, and videos of women bound, taped, and gagged.

Willis was arrested on Tuesday, May 17, and was arraigned Wednesday, May 18.

Investigators are working to determine if Willis has connections to two other unsolved cases out of Muskegon County: the disappearance of Jessica Heeringa in 2013, and the murder of Rebekah Bletsch in 2014.
