Colorado man released from custody without charges in connection with Amber Alert investigation

EDITOR'S NOTE: A previous version of this story stated the man's name, but as he's been released without charges, his name has been removed from the article.

A 19-year-old Colorado man has been released from custody days after police said he forced a 16-year-old girl into his car, prompting an Amber Alert and massive law enforcement search.

The Amber Alert went out around 6 a.m. on Tuesday and was issued out of Boulder. The man was detained later that day, about 25 miles away in Thornton, and the girl, who CBS News Colorado is not naming, was returned to her family. Boulder police officials said the two had a previous relationship.

"Our thorough and ongoing investigation has revealed a number of issues that require additional investigation," a Boulder police spokesperson said on Thursday. "In the meantime, after consulting with the Boulder County District Attorney's Office, the suspect has been released as the investigation continues. This is not unusual, and is indicative of the priority this department places on thoroughly investigating every case."

The spokesperson said the suspect and the alleged victim know each other, and investigators "do not believe there is any active risk to the community at large."

A spokesperson for the Boulder County District Attorney's Office said the man was not formally arrested and does not face charges.

"This individual was released by the Boulder Police Department without an arrest based on additional information revealed in the investigation," the District Attorney's Office spokesperson said. "He does not face any charges at this time and he was never taken to the Jail by the Boulder Police Department because of their thorough and ongoing investigation having revealed a number of concerns that require additional investigation by their department."

Contact information for the man was not available through public records and he couldn't immediately be reached for comment.

A court case related to the charges also could not be located after an extensive search of court records on Thursday and it wasn't immediately clear if he was released without charges or if charges are pending.

CBS Colorado left a voicemail with a Boulder police spokesperson seeking additional comment.
