He ate steak and pasta
Forrest was executed on May 11 in Missouri.
The 66-year-old was found guilty over the killing of two people, Harriet Smith and Michael Wells, during a confrontation over drugs in 2002. He shot both of them in the face at close range, it was reported.
On his last day, he ate steak, pasta, fruit, sliced tomatoes and cucumbers. He drank milk with a slice of chocolate cake for dessert.
Forrest opted not to make a final statement, but witnesses say he mouthed words to his adult daughter, who was watching on behind a glass screen.
