His grandfather and great-grandfather had also served in the Corps of Engineers. He was also awarded a Bronze Star Medal by the United States Armed Forces. a paranoid schizophrenic who was reportedly infatuated with one of the daughters.

He continued to run seminars encouraging people to "use their inner strength and power" until 2015.
