The suspected shooter who opened fire at the store and shooting range in Metairie, La., is among the dead, according to police. Two others who were hospitalized for injuries are in stable condition.
The shootings of the three protesters appeared to change the tenor of demonstrations on Wednesday night. The protests had turned violent a night earlier when two people were killed.
Investigators reportedly say they have evidence that Roy Den Hollander, the FBI's primary subject in the New Jersey killing, was involved in the killing of a rival attorney earlier this month.
