Former CIA employee Mary Embree discusses the infamous heart attack gun. The weapon was first made public during the Church Committee hearings in 1975. Very lethal & untraceable, using this weapon a murder is made to look natural. No doubt the CIA has been using this weapon and has most likely improved upon it since the 70's. Thanks for watching.
