Law enforcement officials said Tuesday that the gunman who went on ain Dayton, Ohio, had been "exploring " and "had a history of obsession with mass shootings." Officials have not made any conclusions on the gunman's motive for the shooting that left nine dead, including his sister.
"The materials reviewed thus far reveal that the individual had a history of obsession with violent ideations to include mass shootings and had expressed the desire to commit a mass shooting," said Dayton police chief Richard Biehl, who held a press briefing along with FBI special agent in charge Todd Wickerman.
"We have uncovered evidence throughout the course of our investigation that the shooter was exploring violent ideologies," Wickerman added. "Based upon this evidence we're initiating an FBI investigation side by side with the Dayton police homicide investigation."
The FBI said there seems to be no "racial motivation" for the massacre.
