Lagoe's body, which was also severely damaged in the military plane crash and being run over by several Tyson Foods refrigerator cars (an Arkansas railroad line ran through his cell), was also found to contain at least two bullet wounds to the head (a rusty, jammed .38 Special revolver was found in his hand). In addition, the autopsy blood tests revealed that jail officials had apparently been withholding Lagoe's heart medication.
Police are still searching for his missing briefcase.
Didn't the article you refer to actually say "two bullet holes to the BACK of the head"?
Not to mention the .45 hole in the top of his head and the indication that someone had bitten his lip.
