William Kogut, an inmate on death row at San Quentin, decided to commit suicide using only the rudimentary tools available to him in his prison cell. He began by tearing up several packs of playing cards, giving particular focus to obtaining pieces with red ink (at the time, the ink in red playing cards contained nitrocellulose, which is flammable and when wet can create an explosive mixture), and stuffed them into a pipe. He then plugged one end of the pipe firmly with a broom handle and poured water into the other end to soak the card pieces. He then placed the pipe on a kerosene heater next to his bed and placed the open end firmly against his head. The heater turned the water into steam and eventually enough pressure built up inside the pipe so that when it burst, the explosion shot out bits of playing cards with enough force to penetrate Kogut's skull, killing him. In a suicide note, Kogut stated that he and he alone should punish himself for his crimes.

Dr. Hitoshi Nikaidoh, a surgical doctor, was decapitated as he stepped on to an elevator at Christus St. Joseph Hospital in Houston, Texas on August 16, 2003. According to a witness inside the elevator, the elevator doors closed as Nikaidoh entered, trapping his head inside the elevator with the remainder of his body still outside. His body was later found at the bottom of the elevator shaft while the upper portion of his head, severed just above the lower jaw, was found in the elevator. A subsequent investigation revealed that improper electrical wiring installed by a maintenance company several days earlier had effectively bypassed all of the safeguards.
