$10,000 REWARD

For information leading to the arrest and conviction in the murder of William "Bill" Sundermeyer

UNSOLVED FOR 40 YEARS, BUT NOT FORGOTTEN

Cold Case Summary

William "Bill" Sundermeyer went missing on June 8, 1985.

Bill never met a stranger, was friendly and generous to everyone. He was always ready to step up to help. Thinking the best of everyone was his guiding light and appears to have been his last mistake. 

His trusty Dodge Rampage, having traveled many states to visit his kids and grandkids was found first, abandoned on a rural road in Phelps County, Missouri and his body days later was found in a ditch in Dent County.


Bill wasn't the victim of a random crime. Investigators believed then-and still do-that he left home with people he knew and trusted. He died alone, far from his family, who have spent the last 40 years with a hole in their lives and no answers.


A proud WWII veteran, Bill raised five children with his wife. He was friendly, warm-hearted, and always ready to lend a hand. 


If you remember anything - any name, detail, rumor, or event, no matter how small -- please come forward. Someone out there knows the truth. It's time.
