Security is on alert at Final Four events in Dallas after fireworks for this weekend's March Madness Music Festival went missing.  

The pyrotechnics were being stored in a staging area on the top floor of a parking garage when they disappeared.  

More than 80-thousand people are expected to attend tonight and Monday's games to crown a college basketball champion.  

The festival features acts like Bruce Springsteen, Tim McGraw, LL Cool J, and others.
