Despite all those factors, he believes time is on the side of law enforcement and as the hours pass, the chance of capturing the man may grow.
Wounded and frightened, the fugitive may have access to water because of the rain, but he is likely without food and getting tired, Nyland said.
"We hope he gets desperate," and turns himself in, he said.
Young's family, in the meantime, continues to hold vigil over the wounded park ranger, hoping for recovery and struggling to find answers to the shooting.
Brody Young's stepmother, Micheline Young, said she was surprised anyone would react to him in a violent way.
"He's just not abrupt," she said. "He would never irritate someone to this point."
The ranger and his wife, Wendy, are residents of Moab and have three children under age 6. He has worked for the Utah State Parks and Recreation Department for 4 1/2 years, according to Utah State Parks spokeswoman Deena Loyola.
"I think we're a little bit in shock," Loyola said. "We've never had anything like this happen. He's one of our own."
Brody Young's father, wife and at least one sister were with him at the hospital this weekend. Members of the family's LDS Church ward were helping to watch the children, Micheline Young said.
"We were told by doctors that they have an excellent team working on him, so we're just hopeful that he'll be all right," she said.
Both lovers of the outdoors, Brody and Wendy Young worked as river guides in Moab after they were married and spent countless hours exploring, Micheline Young said. "They would spend every summer in that area," she said.
David Nordquist, Young's brother-in-law, said it's rare to catch Young without a smile on his face. "He's the nicest guy you'll ever meet," he said.
Micheline Young said her stepson's job has put him in dangerous situations before, "but never alone.
"He was always part of a team," she said. "They would look out for each other."
Sid Groll, law enforcement director with the Utah Department of Natural Resources, said a ranger being shot is rare, though the job increasingly involves dealing with dangerous people.
"We see those things periodically, and we try and avoid those and teach our individuals how to deal with those kinds of circumstances," Groll said. "But sometimes it happens."
Access to the canyon has been shut off and area campgrounds have been evacuated.
