According to the court papers, Johnson stated that after taking time to "chill and do drugs," Adolph and a female companion "began making threatening statements toward Obama," including "statements about killing Obama with a camera with a gun hidden inside the lens. ... Johnson related that Adolf then commented that it wouldn't matter if he killed Obama because he was going to jail on his pending felony charges anyway."
The investigation started after police stopped Gartrell for erratic driving at 1:37 a.m. Sunday, according to law enforcement sources and the court documents.
After checks revealed that Gartrell had a suspended license, police searched the rented Dodge Ram truck he was driving and found two bulletproof vests, wigs, ski masks, walkie-talkies, methamphetamine, a .270 Remington and a .22 Ruger rifle with scope, sources told ABC News. Police said Monday that they believe one of the guns had been stolen.
A law enforcement official told ABC News that Gartrell implicated Johnson and Adolph, whom police later arrested at two separate Denver-area hotels. Authorities said Adolph jumped out a sixth-floor window to avoid arrest. He broke his ankle; medical personnel at a nearby hospital treated him for that injury, police said.
As for the alleged plot to assassinate Obama, sources said that with wind movement and distance, such a shot would not have had a chance of succeeding, and described the alleged plot as "crude."
Additionally, a senior U.S. government official said that the U.S. Secret Service has set up wide perimeter around the venue, which would have kept a shooter from accessing the area, and that guns allegedly in the possession of one of the suspects were not high-powered enough for a shot to travel a long distance.
The senior U.S. government official added that authorities believe the men have apparent methamphetamine problems and would not likely be capable of pulling off any attack.
All three men remain in law enforcement custody pending an initial appearance before a judge.
