Bath salts were all the rage this year, playing a role in too many tragic events. 18-year-old Benjamin Bishop, who has a history of mental issues and bath salts-use, killed his mother, Imari Shibata, and her live-in boyfriend, Kelley Allen, with a sawed-off shotgun following an argument over prescription pills.

Bishop, who had just come home from a 10-month stint in rehab, called police immediately after committing the murders. Bishop was reportedly upset about taking the medication, which he was convinced was "killing him." He pawned electronics to purchase the gun for $279.
