William F. MayerWilliam F. MayerRibbon
Trooper First Class William F. Mayer was 28 years old on that fateful night in August, 1955He had stopped the driver of a pickup truck to warn him that his tail light was not working and lost his life. Trooper Mayer was northbound on U.S. Route 13 at Smyrna, near Duck Creek Bridge, when a tractor trailer struck the vehicle he had stopped, pinning him between the two. William Mayer was born in Wilmington in 1927, attended Wilmington High School and Rutgers University. He met his wife Ria, in Heidelberg, Germany, in the fall of 1946 while in the military. Ria was a displaced person from Latvia. The two corresponded from 1947-1949 until Ria finally arrived in America. After a brief courtship, they married in April, 1950. A member of the Delaware State Police since January, 1949, Trooper Mayer and family moved to Dover where he was stationed at Troop 3. As Ria relates Those short years were so happy for both of us. We hoped for a long life –to grow old together. It wasn’t to be…I know he was proud to be a Delaware State Policeman and loved his work. But…he was much too young to die. Trooper William Mayer was laid to rest in the Odd Fellows Cemetery, Dover, Delaware. He is survived by his wife Ria Mayer, his parents, August P. and Mildred Mayer, and three sisters, Elizabeth, Myrtle, and Margaret.
