From the article:
"The next day, Gricar’s Mini Cooper was found in a parking lot in Lewisburg, about 50 miles from his home in Bellefonte. Gricar’s cellphone was in the car, but not his laptop, wallet or keys, which were never recovered. Months later, the laptop was found in the Susquehanna River without its hard drive, which was discovered later. It was too damaged to yield any information. On the fourth anniversary of his disappearance, investigators revealed that a search of his home computer yielded a history of Internet searches for phrases like “how to wreck a hard drive,” according to a report at the time in The Centre Daily Times"
