I was at the game. At the 10 minute point of the second half (approximately) 4 officers/security guards ran up from section 129 to the concourse. I watched from that section and 3-4 ushers ran to "something" Was it this? I am not sure.
I live here in Madison and ironically my next door neighbor starts on the Memorial basketball team. This is really sad. Sounds like the man was very well thought of.
