Denver • No charges will be filed against Aron Ralston, the Colorado adventurer whose self-amputation ordeal inspired the movie "127 Hours," after he and his girlfriend were arrested in connection with a weekend altercation at her home, prosecutors said Monday.
The girlfriend, Vita Shannon, still faces charges including assault and disturbing the peace. She pleaded not guilty and was released on $550 bail.
Ralston was released earlier. Neither commented as they left jail.
Assistant City Attorney Vince DiCroce said prosecutors reviewed the evidence and didn't think they had a reasonable chance of convicting the 38-year-old Ralston. He wouldn't say why prosecutors decided to continue the case against Shannon, also 38.
Shannon also faces one count of wrongs to minors, a charge used when children are present during an incident but not necessarily hurt. Police said the couple's 8-week-old daughter was present at the time of the altercation. There was no indication the child was hurt. Family members said Shannon's mother has been caring for the girl.
Police documents allege Shannon struck Ralston twice in the back of the head with her fists, and that he shoved her as she was leaving her home. The documents said they were arguing over another one of Ralston's children. Ralston's attorney, Jeff Pagliuca, declined to comment.
Ralston's father, Larry Ralston, told The Associated Press the couple had "a heated argument."
Later, he told reporters, "They're two good parents involved here that care very much for their young daughter."
Each charge against Shannon carries a fine of up to $999 and a sentence of up to a year in jail upon conviction.
Ralston cut off his forearm to free himself from a dislodged boulder in a Utah canyon in 2003.
He was "canyoneering" making his way down a narrow canyon at the time. After five days with little food and water, he broke his arm and then amputated it with a knife to escape.
He detailed his struggles in a book, "Between a Rock and Hard Place," which was adapted into the Oscar-nominated "127 Hours."
Ralston became a celebrity, making inspirational speeches and championing environmental causes.
He also continued his adventurous life using prosthetics he helped develop. He completed a nine-year project to scale the highest point in all 50 states and became the first person to solo climb all 59 of Colorado's 14,000-foot peaks in winter.
