"We are told when someone is drunk at a party to take the car keys away, but Sarah's husband did that and was under penalty of arrest," he said.
"She was driving nine hours, driving up and down the interstate before she went off the road," said Rogers. "She had distinctive car, a Scion, with Florida tags. That stands out. When [Maine police] came across that car, if they'd had some kind of notation they would have expanded their search."
Meanwhile Robert Rogers and his wife, Marguerite, are making plans for Sarah's funeral and wondering how this tragedy could have been stopped.
"I just hope that something can be done to get the authorities to be more responsible for missing adults," Rogers said. "Waiting for 48 hours when things get critical, this just didn't have to happen. It all could have been stopped that day."
