Police say data card shows woman's killing, man in custody

Police in Alaska say a man is in custody after videos were found on a digital memory card depicting a woman being assaulted and killed.

Anchorage police say a caller last week reported finding the card on a city street.

They believe human remains found along a highway earlier this month are those of the woman depicted in the videos.

Authorities are working to identify the woman and her manner of death.

Police say they obtained a warrant for the arrest of 48-year-old Brian Steven Smith on a murder charge and arrested him Tuesday at an Anchorage airport.

Court records did not list an attorney for Smith.
