Austin Reed Sigg was arrested Tuesday evening after police say they received a call that led them to his Westminister home.

CBS Denver reports that police say Sigg, who lived in the same community as Ridgeway, is cooperating with authorities.

The break in he case comes two days after police said Ridgeway's abduction and murder was linked to the attempted kidnapping of a 22-year-old runner in May.

Police say Sigg is being held on two counts of investigation of first-degree murder, and one count of kidnapping in the Ridgeway case. He is also expected to be charged in the attempted kidnapping case.

Sigg will be arraigned on Thursday at 8 a.m.

Jefferson County District Attorney Scott Storey told reporters Wednesday that several agencies, including the FBI, had been working "non-stop, day and night" on the case since Oct. 5, when Ridgeway disappeared on her way to school. Her body was found five days later.
