DAYTON, Ohio (AP) — Authorities are working to piece together what led to a mass shooting in Ohio after accusing the gunman's friend of buying body armor used in the massacre.
Dayton, Ohio officials plan to update on the investigation at a news conference Tuesday afternoon.
Federal authorities announced charges Monday against a longtime friend of gunman Connor Betts. Ethan Kollie is accused of lying on federal firearms forms while buying a pistol not used in the shooting.
Police also accused Kollie of buying armor and a 100-round magazine for Betts. They said there was no evidence that he knew what Betts was planning.
Police said Betts killed nine people including his sister on August 4 before they killed him.
Kollie will appear Wednesday in federal court. His attorney said Kollie was shocked by the shooting.
