A federal judge has ruled the city of Dallas is not liable for an off-duty police officer fatally shooting a man in his own apartment last year.  

U.S. District Judge Barbara Lynn on Monday dismissed the city from a civil lawsuit that the family of Botham Jean brought after the 26-year-old was killed by Amber Guyger.

The ruling leaves Guyger as the sole defendant in the suit that argues better police training could have prevented Jean’s death. It makes a large financial settlement unlikely.

Guyger was found guilty of murder and sentenced to a decade in prison in October.
