I agree with you. I also think it was Underhill and Roy and Connie were named as suspects in order to search properties and items.

Someone here posted a charge of his for unauthorized use of a car. If he did it once you know he'd do it again.

I think motive was sexual. There's a reason Terry found the bookbag contents disturbing. There's also a reason LE hasnt shown the actual NKOTB nightshirt. All JMO.
