Happyshooter,
You're referring to the 1989 shooting in a Renton, WA gun store. The shooter, a young mentally handicapped male, walked past a Renton PD car in the parking lot, into the store and started shooting. There was a Renton LEO in the store who returned fire with with one shot with his Glock 17. Unfortunately, the LEO had just transitioned from a revolver and had his thumb high on his wrist and jammed his gun. My friend, Danny M, high master IPSC shooter and a clerk who worked at the store, opened fire with three shots from his Colt Delta Elite in 10mm. All of the hits, as reported by the coroner (also an IPSC shooter) were A hits. All three shots exited the body, which caused the local paper to report, erroneously, that the shooter had been shot 7 times (4 in, 3 out).
This has been reported in the Ayoob Files in the American Handgunner magazine and I believe is also on the Darwin Awards site.
The sad thing was that the young man had never been in trouble with the law before and his parents had no clue as to why he wanted to go into a gun store and start shooting. As reported, the man was mentally handicapped and was making great progress in becoming independent. There was no civil suit as far as I know (I moved to north Alabama in the summer of '90 and lost touch with Danny). The Renton Police Chief awarded Danny a medal for saving the cop's life.
Ayoob also reports that this was this was the first reported shooting of a human being with the 10mm.
I hope this helps.
Regards,
Merlin
