Court documents in the case of missing Philadelphia woman Kada Scott show text messages with the suspect Keon King.

Amid calls to make the site more secure, Philadelphia crews were clearing debris on Tuesday at the vacant school where the remains of 23-year-old Kada Scott were found.

Less than 24 hours after authorities ruled Kada Scott's death a homicide and charged Keon King with murder, the Philadelphia Medical Examiner's Office reported she died from a gunshot wound to the head.

A rapid DNA test found a 99.9% match to DNA samples collected from Scott's parents, meaning that the remains found on Saturday do in fact belong to Scott.

Kada Scott's father, Kevin Scott, spoke with CBS News Philadelphia as the search for the missing 23-year-old hit the two-week mark since she was last seen.
