Video from the porch of Gretchen Anthony’s Abacoa home shows a tall man lying in wait. When Gretchen steps out onto the porch, you hear muffled shouting, and someone saying What are you doing? In another security video from the home, someone is seen, unmoving, on the floor of the garage. Next to the person is a water jug smeared with blood. Then, a man is seen reaching up to disable a security camera. The man, authorities said in a report released Thursday, is David Anthony, Gretchen’s estranged husband. The Jupiter police report provides numerous items linking Anthony to the death of his 51-year-old estranged wife, last seen March 20. Police said Friday they continue to ask the public’s help in finding the woman. Anthony was booked early Thursday at the Palm Beach County Jail, charged with second-degree murder and kidnapping. On Thursday morning, Circuit Judge Laura Johnson ordered Anthony be held without bond.
