Autopsy Reveals Pennsylvania Killing Spree Suspect Poisoned Himself

An autopsy of the Pennsylvania man suspected of killing six relatives reveals he died after poisoning himself, authorities said Tuesday.

Bradley Stone, who was found dead with self-inflicted stab wounds on Dec. 16 after a manhunt in the Philadelphia suburbs, died of a “combined drug intoxication,” ABC News reports. Authorities said Stone had taken a cocktail of Trazodone, Risperidone and mCPP.

Stone, 35, was suspected of shooting to death his ex-wife and five of her family members, and wounding one more, during the early hours of Dec. 15. The motive remains unclear but legal documents show Stone had recently lost a custody battle against his ex-wife for their two daughters.
