The manhunt for three objectively troubled Florida siblings ended in the Rocky Mountains Wednesday.   The day before they went on the run, Ryan Dougherty was convicted in Volusia County of a sex offense involving a child.  According to police, Dougherty texted his mother, "There's a time for all of us to die."

"It's kind of backwoods around here, plenty of places to hide," waitress and bartender at Viktorio's Pizzeria in Colorado City told the Associated Press.  "What I can't believe it that they were dumb enough to get on the interstate. They could have made it. Then they went and got on the interstate. How stupid," she added.   

29-year-old Lee Grace Dougherty, 26-year-old Dylan Dougherty Stanley, and 21-year-old Ryan Edward Dougherty reportedly purchased camping gear with plans to hide out in the forest.

A nationwide search for the "Dougherty Gang" was initiated Aug. 2 after the siblings reportedly fired at least 20 shots at a police officer trying to pull them over for speeding in Florida.   

The siblings are also suspected of robbing a bank in Valdosta, Ga. hours later.  One of the robbers had an AK-47, the FBI said. 

Colorado State Patrol officials said that the family was spotted trying to buy ammunition for an AK-47 at a Walmart Wednesday morning.

Sheriff Kirk Taylor said that their small white vehicle was also spotted at a gas station in Colorado City .  A deputy followed and called for backup from the Colorado State Patrol, Taylor said.

The family fired AK-47 shots, said Lt. Col. Anthony Padilla of the Colorado State Patrol.

"They just came in, grabbed a few snacks, got gas and left," Clark said. "She couldn't even recall what they got because they just came in like regular customers," 18-year-old gas station employee Jaimie Clark told the Associated Press.

"The fact that they came in here peacefully, we're extremely thankful for," she added.

The suspects were treated at a Walsenburg hospital and transferred to Pueblo County Jail. They will face four charges each on first-degree assault on an officer.
