On Aug. 25, the bloody bodies of a newly
married Santa Rosa couple were discovered at
the end of Old Vallecitos Road in Sunol. Their
assailant or assailants have never been captured.
A motorcyclist found the bodies of Prater,
26, and his bride of two weeks, Mary Ellen, 20,
with their hands shackled tightly behind their
backs. They had .Caliber bullets in their
heads.
Prater was a former convict with a long
record involving sale of narcotics, armed
robber}', burglary and theft, and a warrant
was out for his arrest at the time of his death.
Their red Triumph was apparently stolen,
and it was found later, hotwired and abandoned,

in Oakland. Case unsolved.
