(CNN) -- The list of charges against three siblings nabbed after a high-speed chase grew Friday with a second Colorado county filing allegations against them.
Huerfano County authorities charged Dylan Dougherty Stanley, 26, Ryan Edward Dougherty, 21, and Lee Grace Dougherty, 29, with attempted murder and assault on a police officer. Bond was set at $1.5 million each.
Wednesday's chase was in Huerfano and Pueblo counties. Pueblo filed charges Thursday.
The three also are accused of bank robbery in Georgia and attempted murder in Florida.
Police arrested the siblings after they crashed their car along a rural Colorado highway; police say they were shooting at officers with an AK-47 during a chase at speeds up to 120 miles an hour.
Appearing Friday in Huerfano County court via a video feed from Pueblo County, where they are jailed, the suspects were advised of their rights and waived reading of the charges. A hearing is scheduled for August 22, according to Huerfano County District Administrator Bob Kreiman.
Stanley was charged Thursday in Pueblo County with attempted murder and ordered held in lieu of $1 million bail, while his siblings were each charged with assault and ordered held on $250,000 each. They face an August 15 hearing there.
The siblings waived their right to appear, according to CNN affiliates KGTV and KUSA. A public defender represented them in their absence, according to the affiliates.
CNN left messages for attorney Patrick McCarville, who represents, Lee Grace Dougherty, and Ryan Dougherty's attorney, Michael Emmons. The office of attorney Cobea Becker, who represents Stanley, said she would have no comment.
According to investigators' affidavits, Ryan Dougherty was driving during their effort to elude police Wednesday as Stanley fired an AK-47 at pursuing officers.
"We weren't trying to hurt anyone; we just wanted them to get back," Lee Dougherty told investigators after her arrest, according to one affidavit. "They were way back, and we could barely see them. We were getting shot at, then we wrecked."
Lee Dougherty said she pointed a gun at Walsenburg Police Chief James Chamberlain, according to the affidavit. But Chamberlain fired first, wounding her in the leg.
The trio is wanted in connection with an armed bank robbery in Georgia and the attempted murder of a Florida police officer on August 2.
They escaped from Florida with police in pursuit after they shot out a cruiser's tire, according to authorities.
Colorado authorities said the siblings spent the night before their capture in the San Isabel National Forest, about 10 to 12 miles west of Colorado City.
