The North Korean defector may have just been really drunk
In November 2017, Oh Chung Sung, a defected North Korean soldier, plowed through a Korean People's (North Korean) Army checkpoint attempting to cross the DMZ. KPA soldiers fired on him and his vehicle. When his vehicle crashed, troops closed in and shot him several times. Republic of Korea (South Korean) Army troopers discovered the wounded defector and dragged him to safety.
