On 19 October 2016, a 46-year-old suspect with the surname of Seong started attacking people. He had various weapons, including homemade guns, a bomb, a hammer, and knives. He was wearing an electronic tracking device on his ankle. From Korea JoongAng Daily:
An ex-convict went on a shooting spree in northern Seoul’s Gangbuk District Wednesday night using a gun he manufactured himself, fatally shooting a police officer before he was apprehended.
The ex-convict was wearing a type of bullet-proof vest and helmet and had with him 16 more homemade guns, a bomb and seven knives.
The suspect, a 46-year-old surnamed Seong, was wearing an electronic tracking device on his ankle when he started attacking people near Opaesan Tunnel in Beon-dong. He had a record of prison sentences for sexual assaults.
Seong allegedly shot a passerby with a homemade gun and missed him, although another passerby was hit. Seong then bludgeoned the first passerby with a hammer.
While this event occurred six years ago, it is worth recording as another murder with a homemade gun. It is possible the assassin of former Prime Minister Abe knew of this murder.
Another report says the suspect had six guns. The killer is reported to have made a bomb as well. He was wearing a “bulletproof” vest used in paintball games. The vest was said to be effective in stopping three police bullets. He was also wearing a helmet, origin not stated.
The article from Korea does not show how the propellant for the homemade guns was ignited. The article explains the mechanism as a simple matchlock, or perhaps a sophisticated hand canon, that was ignited by a similar method.
