Herrmann, 61, was supposed to be in Hawaii right now visiting family.

"Lengyel was in Capitola around the time of her disappearance," said El Cerrito Police Chief Paul Keith. "He came back to El Cerrito, and then traveled to Portland Oregon by car."
Detectives think he is back in the Bay Area, but still do not know how to get ahold of him.
They say they have evidence that suggests this is a homicide case.

"We are trying to determine where he may have gone in that time frame," Keith said. "With hope of finding some clue where Alice is at."
The Herrmann family is not losing faith of finding Alice.
