Denver • The sister among three Florida siblings wanted in a multistate crime spree was sentenced Monday to 24 years in prison for a shootout in Colorado.

Lee Grace Dougherty, 29, had faced a maximum of 28 years in prison after pleading guilty to first-degree assault and two counts of menacing.

Earlier Monday, her brother Dylan Stanley-Dougherty received the maximum prison sentence for his guilty plea to one charge of first-degree assault. The third sibling, 22-year-old Ryan Dougherty, was to be sentenced later in the day.

The three are accused of shooting at a police officer and staging a daring bank robbery in a cross-country crime spree that included Georgia and Florida. The manhunt for them ended in Colorado — Monday's sentencing effectively ends their stay in this state as Georgia authorities await their extradition.

The 27-year-old Dylan earlier pleaded guilty to charges related to the Aug. 10 freeway chase and shootout with police in southern Colorado, as did Lee Grace Dougherty and Ryan Dougherty.

Once the judge in Colorado hands down Ryan Dougherty's sentence, the U.S. Marshals Service will transport all three to Albany, Ga., for a May 15 court hearing.

Ryan pleaded guilty to five counts of menacing and faces up to 20 years in prison.

As part of plea deals, Colorado prosecutors agreed to drop multiple counts of attempted second-degree murder against the siblings that could have carried a maximum of 48 years in prison on each count.

Prosecutors also agreed to allow the judge to consider sentences that would let the siblings serve their Colorado prison time concurrently with any sentences they may get in Georgia and in Florida.

In Georgia, the siblings face firearms and other charges in an Aug. 2 bank robbery in Valdosta. Witnesses say two men and a woman, dressed in black and wearing masks, entered the Certus Bank branch just over the Florida state line and fired shots into the ceiling. One carried an AK-47 type assault rifle and an automatic pistol, similar to weapons recovered after the siblings' capture in Colorado.

The siblings later told investigators that Lee Grace Dougherty was to be the lookout and keep the bank's door open, Dylan was to take control of the room, and Ryan's role was to jump over the counter and take the money, authorities said.

The trio made off with about $5,200 and had spent about $1,000 of it by the time police caught up with them in Colorado, authorities said.

Sue McKinney, a spokeswoman for the U.S. attorney for the Middle District of Georgia, did not return a message seeking comment.

The three are charged with firing shots at a police officer in Zephyrhills, Fla., some 210 miles south of Valdosta, during a high-speed chase earlier on Aug. 2.

In Florida, all three siblings are charged with fleeing or eluding and attempted second-degree murder of a law enforcement officer. Convictions could mean life sentences, according to court officials. Ryan Dougherty also is charged with grand theft auto.

Authorities in Florida said all three siblings had been living together in Lacoochee, about 45 miles northeast of Tampa, and each had a criminal record.

Before the alleged crime spree, Ryan Dougherty had just been sentenced to register as a sex offender for sending sexually explicit text messages to an 11-year-old girl. His mother, Barbara Bell of East Palatka, Fla., said her son feared the conviction would prohibit him from seeing his newborn son.

Dylan Stanley-Dougherty's lawyer, Kobea Becker, portrayed him as a loyal family member who was desperate to help Ryan. Judge Claude Appel didn't buy the explanation.

"You're saving your brother from a probation sentence, for crying out loud, not a prison sentence," he said of the siblings' efforts to prevent Ryan from having to register.

Bruce Bartlett, chief assistant state attorney for Florida's 6th Judicial District, said authorities there are seeking extradition.

"We'll be seeking sentences that ensure they spend most of their life in prison, if not all of it, so if and when they were to get out of prison they would no longer pose a threat to everyone," Bartlett said in a phone interview.

Ryan Dougherty told authorities in Colorado that the trio hoped to escape to Mexico. They siblings told investigators they traveled across the country in a stolen car, taking back roads to avoid detection.

Lee Grace Dougherty was shot in the knee when she pointed a gun at a police officer after the trio rolled their car on Interstate 25 in Colorado. "I deserved to get shot," she told investigators.

Prosecutors say that Dylan Stanley-Dougherty was the one who fired an assault rifle at pursuing officers before the siblings' capture in Colorado and was also the one who fired at a police officer in Florida and a bank robbery in Georgia. During the hearing, he told the judge that he was sorry and didn't want to hurt anyone.

"I never intended, I never tried to, I never wanted to hurt anybody. It is true that I acted out of desperation and I am sorry for choices that I made," he said.
