DENVER -- A Colorado Springs aid worker remains missing nearly a week after the Haitian earthquake, but colleagues stressed Monday that he had a backpack with water bottles and granola bars that could sustain him.

Colleagues of the Compassion International videographer, David Hames, are urging rescue workers to keep searching the rubble of the Hotel Montana, where they hope he'll be found alive. News reports over the weekend said workers were still hearing signs of life from collapsed hotel, including whistling and tapping.

There is reason for hope: Hames' colleague, Dan Woolley, also of Colorado Springs, was rescued from an elevator shaft at the hotel Friday morning.

Compassion International on Monday released a photo of Hames and Woolley having breakfast atop the Hotel Montana the day of the quake. Colleagues pointed out that Hames' backpack, containing water and snacks, was sitting near the videographer in the photo.

"That gives me hope that he can hold out," Mike Westphal, Hames’ agent, told the Colorado Springs Gazette.

However, an ABC News team reported from the hotel site Monday that authorities were deliberating on whether to shift from a rescue effort to a recovery mission.

An unidentified Ecuadorian Army captain told ABC there are no more survivors.

The captain believes there are 100 bodies entombed in the ruins of the Montana, which was a top hotel for Westerners, ABC reported. He said many died in the gym and at the bar, having just returned from work when the earthquake struck.

If officials decide that the hotel site is now a recovery mission, it would be a blow to the search for Hames, because authorities might bring in heavy equipment to move large chunks of debris to remove bodies.

This could pose a hazard if anyone were still alive in the debris.

Sieben that Hames wife, Renee, is holding up well given the circumstances.

"Renee has an amazing group of people surrounding her with love and care," he told The Gazette. The Hameses have two children, ages 3 and 5.
