Willis hasnt talked to authorities since he was taken into custody, and his home, van and another property, once owned by his grandfather on Bailey Street in Norton Shores, were searched for evidence.
Muskegon County Undersheriff Daniel Stout said the evidence seized makes Willis a suspect in Heeringas disappearance and Bletschs homicide, but he would not reveal specifically what investigators found that led them to that conclusion.
The weapon is a similar model that would have shot the bullets in the Bletsch case, Stout said. Similar
but similar is a big word.
Hundreds of items, including computers, multiple phones, clothes and documents, are being analyzed along with evidence recovered from the van, including the pistol.
Investigators say they found locked boxes when they searched Willis' 2006 silver Dodge Grand Caravan. Officials said one had handcuffs, chains, rope, five syringes including one with liquid, possibly a sedative photographs of females chained and bound, a mask and rubber gloves and another had a gun with the serial number destroyed.
