July 1, 2012
Grocery Store Camera exhibits at 4:18 pm were introduced (NOTE: These two exhibits probably shown to verify his hair was/was not colored, but I could not see on my computer monitor today whether hair was orange in the photos - nor did I hear today that he ever purchased hair coloring)

First sighting of Holmes with orange hair - James Holmes' dyed orange hair became infamous after his first appearance in court. According to testimony from Steven Beggs, Holmes had already dyed his hair when he bought a scope at a Gander Mountain store on July 1.
