DENVER (AP) - Authorities say one of three siblings who were part of a crime spree and nationwide manhunt planned to escape from a Colorado jail.

They say Dylan Stanley Dougherty got out of his cell through a plumbing access panel and got a note to his sister telling her he was going to break her out of jail.

He faces charges of conspiracy to escape and possession of contraband for the alleged escape plan discovered during January 10 search.

According to an arrest affidavit, deputies found a homemade knife and letter to the FBI in his cell. A deputy who followed the plumbing into the ceiling found footprints, as a well as a note to Lee Grace Dougherty saying he planned to subdue guards, steal their keys, and escape with her.

The siblings, who call themselves the Dougherty Gang, are accused of firing around 20 shots at a police officer in Zephyrhills before launching a high-speed chase.

Investigators say the trio later held up a bank in Valdosta, Georgia, before finally getting into a showdown several days later in Colorado.

When told of the escape attempt Friday, Pasco County Sheriff Chris Nocco remarked to 10 News in an email, "Sad, but not a surprise from this crew."
