A double murderer smiled and laughed at the family of his victims moments before he was executed in a "botched" procedure that took nearly two hours.
Joseph Wood was convicted of the murder of his ex-girlfriend Debra Dietz and her father Eugene Dietz on August 7, 1989 after walking into their family-owned car body store in Tuscon, Arizona and shooting them.
Debbie, 29, had issued a restraining order against Wood after a turbulent five-year relationship between the two, including alleged acts of domestic violence against her.
