A trace of the two guns found by investigators at the scene revealed that suspect Brandon Scott Hole, 19, の インディアナポリス, legally bought the rifles in July and September of last year, officials with the Indianapolis Metropolitan Police Department said Saturday.
IMPD did not share where Hole bought the guns, citing the ongoing investigation, but said Hole was witnessed using both rifles during the assault.
Deputy Police Chief Craig McCartt said Hole began firing randomly at people in the parking lot of the FedEx facility late Thursday, 四人殺し, before entering the building, fatally shooting four more people and then turning the gun on himself.
Paul Keenan, special agent in charge of the FBI’s インディアナポリス field office, has said that agents questioned Hole last year after his mother called police to say that her son might commit “suicide by cop.” He said the FBI was called after items were found in Hole’s bedroom but he did not elaborate on what they were. He said agents found no evidence of a crime and that they did not identify Hole as espousing a racially motivated ideology.
