DENVER (Reuters) - One of three Florida siblings accused of shooting at police following a cross-country crime spree pleaded guilty in a Colorado court on Thursday to reduced charges, court documents show.

Lee Grace Dougherty, 29, who was initially charged with attempted murder, pleaded guilty to two counts of felony menacing and attempted first-degree assault, according to a plea agreement filed in Huerfano County District Court.

Lee Dougherty and her brothers, Dylan Stanley Dougherty and Ryan Dougherty, were targets of a nationwide dragnet last summer for the attempted shooting of a Florida police officer and for a Georgia bank robbery.

The trio was arrested in southern Colorado last August after a high-speed chase and running gun battle with police.

Lee Grace Dougherty faces between nine and 28 years when she is sentenced April 30.
