Students burned, mysterious cause, KATC, February 11, 2011:
"We just kept trying to find answers," Hathaway High Principal Mona Miller said. ...
"It's very bizarre." [parent Donald] Demary says, "it's something we need to be very concerned about."
"It looked more like a flash burn." Miller described, "or something someone would experience inside a tanning bed."
School officials say it could've been the lighting, allergic reactions or even chemicals.
