Pierce County prosecutor Sunni Ko said in charging documents that Price Miller Jr. may have made a suicide pact with his victim in case anybody found out about their relationship, and added that the process of uncovering evidence against Miller is not over.

Miller began a sexual relationship with a neighbor boy, who was not in his troop, when the boy was 7- or 8-years-old, prosecutors said.

It ended recently when the alleged victim turned 15 and told a counselor about the relationship.

By law, the counselor told police. But the alleged crime has startling overtones.

"He discussed the possibility that they would be both better off if they committed suicide," said Pierce County Deputy Prosecutor Mary Robnett.

Miller is an assistant scoutmaster with Troop 47 based at Fircrest United Methodist Church. He was charged Friday with multiple counts of child rape and child molestation.

Investigators say in the last few weeks, Miller may have been burying evidence of other molestations on his 60-acre ranch near Eatonville, which includes a cave where some of the alleged sex crimes took place.

The troop's Scoutmaster finds that hard to believe.

"We were aware of the cave just recently," said Troop 47 scoutmaster Randy Unruh. "The burying of boxes and stuff... I'm kind of wondering if that's covering evidence or getting ready for a treasure hunt or something."

Unruh said the troop, which has included about 20 boys over the last couple of years, would routinely have campouts on Miller's property. Prosecutors say there's no evidence right now that he's molested a troop member because the victim was just a neighbor of Miller's.

"They have had a very, very close relationship," Robnett said. "Spent significant time together -- more time than the defendant has spent with his own family essentially."

The judge agreed with prosecutors that Miller was a potential flight risk at set bail at an extraordinary amount of $1 million.

Saturday, dozens of investigators will be searching Miller's Eatonville ranch for that possible buried evidence.

Investigators also believe there could be more victims out there.
