A federal judge is dismissing another suit filed against law enforcement officials by a family of a student wounded in the Columbine High School shootings.
The judge ruled last year that Jefferson County sheriff's officials had immunity to the suit. He said they responded reasonably to the shootings.
The family alleges officers failed to investigate threats and crimes by the Columbine gunmen a year before the rampage -- and then botched the response.
The judge dismissed three other lawsuits against the sheriff's department last week.
Eric Harris and Dylan Klebold gunned down 12 students at the school in April 1999 before killing themselves.
