Aurora Batman shooting: Footage of alleged shooter at science camp released

A six-year-old video shows Colorado shooting suspect James Holmes as a thin teenager wearing an oversized shirt and occasionally breaking into a slight, shy smile.

ABC News aired the video today showing Holmes speaking at a science camp at Miramar College in San Diego when he was 18.

His presentation is on “temporal illusion,” which he defines as “an illusion that allows you to change the past”.

He says he studies subjective experience, calling it “what takes place inside the mind, as opposed to the external world”.

A woman who introduces Holmes says he wants to become a researcher and make scientific discoveries.

She says his dream is to own a Slurpee machine, which dispenses frozen flavoured drinks, drawing laughter from the audience and a smile from Holmes.
