MUSKEGON, Mich. - Authorities are looking into a man's history after he was arrested and charged in the attempted abduction of a teenage girl.
On April 16, the victim says she was lost and that's when Jeffrey Willis offered to let her use his cell phone.
She told investigators she got into his van, and that's when he took off and locked the doors.
When he pulled out a gun, she says she was able to unlock her door and escape.
A short time later, Willis was arrested and charged with the crime.
Court documents obtained by WXMI paint a disturbing picture after detectives searched Willis' home.
While searching through Willis' van, investigators say they found a locked box containing handcuffs, chains, rope, a mask, rubber gloves, a bar with wrist restraints and a ball gag.
Authorities say they also discovered five syringes, including one that contained liquid.
In a separate box, police also found a .22 semi-automatic pistol with the serial numbers removed.
Now, the prosecutor's office says they are looking into whether Willis may have played a role in two of the area's most well-known cold cases, including the disappearance of Jessica Heeringa in 2013 and the murder of Becky Bletsch in 2014.
At this point, they say they do not have any evidence that ties Willis to those cases.
Jeffrey Willis was formally charged Wednesday with one count of kidnapping, one count of assault with a dangerous weapon and two counts of felony firearms.
