PAMPA, Texas (AP) - An expert witness for Hank Skinner says DNA evidence in his case has degraded and would have exonerated him of the deaths of his girlfriend and her two sons if stored properly.
Julie Heinig testified in a state district court in Pampa on Monday as attorneys for Skinner seek to spare him a lethal injection. Skinner was convicted of capital murder in 1995 in the 1993 deaths of Twila Jean Busby and her mentally impaired sons, Elwin Caler and Randy Busby, at their Pampa home.
She testified that she reviewed the DNA evidence recovered from the house and said it had degraded from being stored in plastic bags in an environment where temperatures weren't properly controlled.
Attorneys for the state say the DNA confirms Skinner's guilt.
