An Ohio woman who was on her way to Graceland never made it — but no one is quite sure where she ended up.
However, he first told authorities that he turned her body over to EMS workers — but now says he dumped his dead wife in a river.
The mystery surrounding Roberta's whereabouts began on Jan. 9, when police received a concerned call from her brother, Brian Heisler.
According to Philip, when Roberta died in Memphis, he pulled over and asked an EMT for help.
Philip claims his wife was taken to an unknown location after paramedics confirmed she was dead.
But after speaking with EMS companies, hospitals and medical examiner offices in the Memphis area, police determined no women matched Roberta's description.

When confronted with that information, Philip said his wife died of natural causes — and now claims to have "put her with nature" by throwing her off a bridge on Interstate 40 into the Tennessee River.
The Benton County Sheriff's Office has been searching the area for her body, but Roberta has not been found.
No charges have been filed against her husband of 53 years, as authorities continue their investigation — which is still considered a missing persons case.
The FBI was also asked to conduct a polygraph on Philip.
