(AP) - An Indiana State Police spokesman says a 14-year-old boy who exchanged gunfire with officers at an eastern Indiana middle school before taking his own life wasn't a current student at the school.

Capt. David Bursten says authorities aren't ready to release additional information on the suspect or the weapon he used during the Thursday morning shooting.

But he says officials are "very, very grateful" that someone had alerted authorities earlier in the morning about a potential for violence at Dennis Intermediate School in Richmond. Bursten said at a news conference that the tip meant the school was on lockdown when the teen arrived and tried to enter the school.

He says the teen shot out glass in a school door and entered. Officers followed the boy and exchange gunfire with him inside the school before the teen took his own life.
