Boyfriend of missing Florida woman charged with murder: "We wish Collin would provide us the information of where Kathleen is"

A man has been charged with second-degree murder in the case of a missing Florida woman who disappeared a week ago. 

Pasco County Sheriff Chris Nocco said at a news conference Monday that Collin Knapp, 30, was arrested after tests showed blood on his clothing linked to 34-year-old Kathleen Moore.

Moore's body has not been found and Knapp is not cooperating in that search, Nocco said. He added that Knapp has had 10 felony arrests since 2004, including for domestic violence and assault allegations.
