 Good morning, I'm Bill Walcher, KBNU News. Provo Fire and Rescue is taking the lead on investigating why fireworks went into the crowd at Lavelle Edwards Stadium last Thursday, injuring multiple people. Provo City Fire Marshal Lynn Schofield says he was at the Stadium of Fire show when the incident took place. He explained there was a malfunction of one of the fireworks in the pyrotechnic display that caused the discharge of fireworks into the crowd.
