Police think carbon monoxide poisoning was a factor in deaths

— Police confirmed Saturday that they found the bodies of Page Stockdale and Mark Schiebel in the back of a pickup in the Sarvis Creek parking area south of Steamboat Springs.

“It is suspected, at this early stage in the investigation, that carbon monoxide poisoning is a factor in the deaths. …" Steamboat Police Chief Joel Rae said in a news release.

All of the windows to the truck topper were closed, and there was a charcoal grill in the back of the pickup.

Rae later said over the phone that "ruling a suicide, murder-suicide or accidental carbon monoxide poisoning (as the cause of death) would be purely speculative at this point in the investigation, and we would hope to determine the cause of death in the days and weeks ahead."

Rae said that autopsy and toxicology tests would be done in the coming days, and the investigation into the deaths is ongoing.

Investigators with the Colorado Bureau of Investigation arrived Saturday afternoon to help process evidence.

The truck was discovered by two Routt County men who were duck hunting in the area. Police were notified at about 8:30 a.m. Saturday

Stockdale was reported missing Tuesday night after not showing up for a dinner date. On Wednesday, she did not show up for a physical therapy appointment, and on Thursday, she neither boarded a plane nor canceled her ticket for a trip to Vermont.

In recent months, Stockdale had been seen driving a black Toyota Tacoma pickup with a topper and grill guard. The truck belonged to Schiebel, 59, who has lived in Steamboat for about 15 years.

On Friday, police searched Schiebel's home but did not immediately find anything.

"We're heartbroken," said Kathrine Warren, Stockdale's niece, who was one of the last people to see Stockdale. "We had thought of all possible outcomes. We really would have loved to have found her safe."

Warren, who lives in Telluride, said Stockdale's two brothers and stepson were in Steamboat to help with the search.

"We're very grateful to the Steamboat police for all their hard work and trying to get to the bottom of this," Warren said.

Schiebel's brother, Barry Schiebel, who lives in Fort Collins, was not available immediately for comment.

"There is a whole community that is grieving right now," said John Lamb, one of Stockdale's close friends.
