This is sad on what is saying he did this part here
Police honed in on Zandstra as a suspect in January, when investigators interviewed an unnamed witness who was best friends with his daughter when Gretchen disappeared, according to a criminal complaint. The witness said that she often went to sleepovers at Zandstra’s home, and during one about a week before Gretchen’s disappearance, Zandstra molested her. When the witness told Zandstra’s daughter what had happened, she told her friend that Zandstra “does that sometimes,” the complaint said.
David Zandstra is being charged with first-degree murder, kidnapping, and other related charges, according to court records.
