WASHINGTON (AP) -- D.C. police say they have arrested the former boyfriend of a woman who disappeared eight years ago. Authorities say Jose Angel Rodriguez-Cruz was arrested Friday and charged with killing 47-year-old Pamela Butler.
Butler, who worked for the Environmental Protection Agency, disappeared from her Northwest Washington home in February 2009. Butler's body has never been found, but a judge declared her dead last July.
After Butler's disappearance, police questioned Rodriguez-Cruz, whom she had met through on online dating service. Authorities reopened the case in February, but it was not immediately clear what led them to arrest him this week.
Rodriguez-Cruz is expected in court on Monday.
Rodriguez-Cruz, a former military police officer, has previously denied any involvement in Butler's disappearance. FOX 5's Paul Wagner covered this story when it broke, and recently for our Rewind to the Crime series.
