A man in Shreveport, Louisiana killed eight children aged 18 months to 12 years in a domestic violence shooting across two homes early Sunday morning before being shot and killed by police. The victims included seven of the suspect's own children and one family friend; his wife and another woman were also shot and seriously injured. This is one of the nation's deadliest mass shootings in over two years, with police describing the crime scene as 'extensive' and noting most children appeared to be shot while asleep.
