This one is an oldie but a goodie. Ricardo Alfonso Cerna was a 47-year-old Guatemalan immigrant who shot himself point blank in the temple with a .45 caliber pistol he had hidden in his waistband while sitting in a interrogation room in the San Bernardino County Sheriff’s office in Muscoy, California. Cerna was stopped for a traffic violation on December 19, 2003, by Sheriff’s Deputy Michael Parham. For some reason Cerna tried to escape and Parham pursued him. Cerna shot Parham twice in the stomach and was caught soon after. Although Parham did not die, Cerna was aware that he was going to have a third strike case which is a mandatory life sentence. So, instead of spending the rest of his life in prison, Cerna chose to end it with a gun he had snuck into an interrogation room. Three different law enforcement agencies were part of the chase to catch Ricardo Cerna, and not one of them made sure to pat him down and search him. Good job, guys.
