Whatever happen to Dale Smith?

He invented the “fuzzbuster” brand radar detector and owned Electrolert inc. He was a vicious critic of police radar, and wrote several books on the subject and was considered to be an expert and even testified many times as one. Electrolert has since been sold several times, and police radar has changed much over the past 30 years. With the introduction of police laser guns I figured we’d hear something from him, but I’ve heard or read nothing. Is he dead? A web search reveals about 50 gazillion Dale Smiths.
Any clues?:confused:
