The following is a composite of eyewitness testimony from those present during the 1 February 2013 CFB/PHYS 3333 class(*).

The suspect is a thin white female man, aged from 22 to late 40s, weighing between 120 and 200 lbs, with height somewhere between 5'6" and 6'1". (Well, that narrows it down!)

The suspect was dressed in unusual clothing as a clown or a cross-dressing alien, with either a brown fur coat or a colorful jacket, a knit red or orange beanie hat with a yellow pom, and either a long purple skirt or pajama pants. The face was covered by a cloth, handkerchief, scarf, or ski mask. It was wearing thin-framed green sun glasses or strange safety glasses. The hands were covered by gloves or brown mittens. Every square inch of skin was covered and this is how we can be sure that the perp was Caucasian.

There was a necklace made of purple and green construction paper loops and there were feathers on the back of the head. A sign taped to its back said, "Pick my nose."

The suspect entered from the back of the room and walked silently with loud footsteps toward the front desk where it took a model of molecule and left a lemon in its place.

The suspect then left through the front door of the classroom. The whole event took anywhere from 2 seconds to 15 seconds.

Did anyone get a picture?

(*) The above is based on the eyewitness testimony of 21/48 students. 27/48 students observed nothing related to the events conducted by the suspect. Of those 27 students, about 5 were late to class and of the rest, about 2 or 3 were hallucinating. Seriously, you should not drop LSD before coming to class.
