Perp Male (confirmed).
Back to WTAE, interviewing a very poised young man, Ritchie. He said he does NOT want to spread rumors, but did confirm that fire alarm was pulled to get students into hallways. This kid is very calm and poised.
Prayers said. Thank you PAmom for the updates. I know the area well. My orthodontist was located just down the street from the high school. Murrysville is a very nice area...one we couldn’t afford to live in
