BOULDER, Colo. -- Police searched the Boulder home of the parents of missing Marine Lance Cpl. Lance Hering on Tuesday but didn't find him.

Police recieved a tip from the military that Hering might be at his parents' home in south Boulder, according to police spokeswoman Julie Brooks.

Hering was reported missing last October after his friend, Steve Powers, told police that Hering fell while the two were hiking together in Eldorado Canyon, but he said when he returned with help, Hering was gone.

That prompted the largest search effort ever in Boulder County, encompassing the canyon area southwest of Boulder.

Powers later told police the story was fabricated and that Hering staged his own disappearance to avoid returning to duty and to Iraq.

He was videotaped buying a bus ticket at the Denver bus depot the same day of his disappearance. Hering purchased the ticket using an alias name, police said.

Hering has two outstanding warrants out for his arrest including a felony charge of failure to comply with the terms and conditions of a deferred sentence stemming from a 2004 burglary arrest. The other warrant for his arrest is for conspiracy to commit false reporting to authorities.
