Rex Krebs

At the Clovis Cemetery, Aundria Crawford's tombstone features a photo of the former Cuesta College student sandwiched by images of ballet slippers and a barrel racing horse.

As he walked up the driveway to greet his parole officer, Rex Krebs was remarkably calm and collected, even though a missing woman's body lay buried just yards away outside his rural Avila Valley home. The agent, David Zaragoza, stepped out of his four-wheel-drive truck and eyed the shoulder harness Krebs was wearing.

Once considered for demolition, the two houses where Rex Krebs committed his crimes still stand, tragic reminders of what happened in rural Avila 10 years ago.

Though he was sentenced to death in 2001, Rex Krebs could remain on California's death row for 15 more years or longer.

In the summer of 2001, a sheriff's deputy dropped Rex Krebs off at San Quentin State Prison with a sardonic message.

In the weeks after Rachel Newhouse disappeared, Allan Krebs says he remembers seeing missing-person fliers featuring her photo.
