Also happened in Slovakia.

One I had recently heard of happened in Čachtice in 2023.
48 year old ex police officer was cleaning a rifle, when it fired, shooting through a window, and killing a 30 year old mother who was in a kitchen of opposing building 120m (394ft) away.
Less than a month ago he received a 2 year prison sentence suspended for 3 years, and a ban on owning and using firearms for 8 years.
