The suspect in the Indianapolis mass shooting was known to federal and local authorities prior to the attack. A family member of the suspected shooter reached out to authorities warning about the suspect’s potential for violence, according to three law enforcement sources briefed on the matter. It was not clear when the warning was given but the outreach was followed up by both local authorities and FBI, which opened a preliminary investigation into any possible threat, the sources said. The FBI is helping Indianapolis Metro Police Department “on the search of the suspects home,” the FBI special agent in charge Paul Keenan said at a Friday morning news conference. “Well once we positively identify who he is, we will be able to research further,” spokesperson Genae Cook said.
