Info

John william “bill” cliborn, age 47, was the kind of solid, reliable guy you’d expect to see running a fledgling company. A devoted family man, bill had previously served as a security guard, as well as a reserve officer for the littleton police department. As coowner of lan resources, bill’s meticulous, organized personality lent itself well to running the company’s quality control. On a cold and icy evening, march 10, 1988, bill was allegedly last seen around 6:00 p.M., and spent his last hours alive working late in his inverness business park office located at #14 inverness drive, b120. A short time later, two of the company’s project managers returned from completing a job downtown and were greeted by a horrifying scene. Bill cliborn lay sprawled on his office floor, bloody and viciously bludgeoned to death. Investigators later found nothing in bill’s office to be stolen or disturbed, and the evidence pointed toward some solid suspect information. To date, it has not been disproved that bill’s cold-blooded murder was committed by someone he knew.
