The sister of a man feared dead after a body was found inside his burned-out cabin on Dead Indian Memorial Road early last month is offering a $20,000 reward for the arrest of whomever is responsible for the suspicious disappearance of David E. Lewis.

Two fires — at 18196 and 12801 Dead Indian Memorial Road — were reported about an hour apart in the early morning hours of Sept. 4. Both houses burned to the ground and a man's body was found inside the cabin at the summit, where Lewis, 46, had lived for more than two decades. The other cabin, near the intersection with Keno Access Road, was a summer home occupied only on weekends, neighbors and authorities said.

Theories have circulated through the mountaintop community, but no arrests have been made and the identity of the body found in Lewis' cabin has not been positively confirmed.

Now, family and friends are joining police in continuing the search for details about the shocking crimes.

David Lewis' friends and family, fearing the worst, held a memorial for him on the mountain Sept. 14. Lewis' sister, Linda Lewis Miller, has posted the $20,000 reward for information leading to an arrest in the case. She also posted a $5,000 reward for "pertinent information leading to an answer," said Donna Allen of Ashland, in an e-mail to the Mail Tribune Wednesday.

Miller could not be reached for comment.

Allen said she is creating a MySpace page to look for answers to her friend's disappearance. Lewis' page will be placed under the heading of missing and unsolved murders, Allen said.

"I also have him listed on some Web sites about unsolved cases," Allen said.

Jackson County Sheriff Mike Winters has said it was an odd set of circumstances to have two residences burn down at the same time in this remote location. Winters said Wednesday the reward might help shake loose further information regarding the pair of suspicious house fires.

"I don't think this hurts the case. We offer rewards often for cases on CrimeStoppers (of Southern Oregon)," Winters said.

Investigators have contacted several local dentists, but couldn't come up with recent dental records for Lewis, he said. DNA samples from the body found in Lewis' cabin and from Lewis' family members have been sent to the University of North Texas Center for Human Identification, a national program supported in part by the Department of Justice. Results have not been returned, Winters added.

An autopsy was done, but Winters declined to release the cause of death. He said details of the investigation can't be made public, but said detectives are tracking down every clue.

Winters owns property and spends time in the rural area in the mountains east of Ashland. He said he has no information to indicate people or homes there are at any additional risk.
