 As evidence shows, she vigorously struggled while she was in the grave and was likely conscious for up to five minutes after being buried. The 39-year-old disappeared while she was in the process of divorcing Pagniato in May of 2017. County sheriffs say cell phone evidence shows David was in the gravesite area days before his wife went missing and the night of the kidnapping. Detectives say he wrote two notes pretending to be Sandra, saying she was leaving David, their cars, home, and kids, but forensics show he wrote those notes. Sandra's body was found days after she disappeared.
