SAN ANTONIO -- The search for a San Antonio man continues after he went missing while hiking in Rocky Mountain National Park.

Troy Green, 39, went to Denver last week for a conference but never showed up. When his wife hadn t heard from him, she called police. Green's rental car was found at the park on Friday, but Green nowhere to be found.

On Sunday, officials said a tip came in that hikers had seen him Thursday afternoon. Search efforts began Friday and continued Sunday, but with no sign of Green.

He was not prepared to spend the night out. He was out for a day hike with very minimal gear, said incident commander Rich Browne. The weather that Mr. Green was out in was sub-zero with wind chill factors very low.

Back in San Antonio, those who know Green are worried sick. A Facebook page has been started for friends and families to leave their prayers.

Neighbor Lea Robinson described Green as caring and unselfish.

He would do anything for you. He helped us in a lot of situations around the house, or technical stuff, Robinson said. He was the kind that would do anything to help out.

They would love to help bring Green home. But hundreds of miles away, all friends can do now is pray.

Just hoping, hoping for the best, Robinson said. Crossing my fingers that something happened, that they find him and he will be able to come home.

Officials said they are using helicopters and K-9s to search for Green. They plan to continue searching Monday.

Rocky Mountain National Park is about 65 miles northwest of Denver.
