Safariland ALS, as shown:IMPD Det. Tom Lehn described the incident as a "very freak accident," and "something highly unusual in my 31 years in law enforcement."
...
Lehn said as two IMPD officers stood up to leave - their seats very close together - the one officer's holster somehow became entangled with either keys or a radio antenna hanging from the other officer's equipment belt
He said when the one officer stood up, the keys or antenna got caught in the holster and pulled on the trigger, discharging the gun. The bullet struck the deputy sitting behind the officer in her knee.
