Investigators would not say how Bonnie Snook died, but they are calling her death a homicide, and have a person of interest in custody. That person is at the Snyder County Prison on a parole violation.
"Yeah they were nice people. They were quiet. We had no problems with them at any time," said Jerry Wetzel, a neighbor.
Jerry Wetzel and his wife Sharon have lived down the street from the couple for almost 35 years. The Wetzels heard about the homicide from another neighbor, and said it hits too close to home.
"Yeah, you don't think of it happening in your own neighborhood, that's for sure," said Sharon Wetzel. "I never would have imagined something like this happening this close to our place, being out here with the neighbors we've known for years and years. It doesn't seem like it would happen around here, but it did."
Investigators said this was an isolated incident, and the public is not in any danger.
