New web phenom: The Trayvon Martin truth squad

While other people watch reality shows, a marketing specialist in Michigan who goes by the name “Bcclist” spends time in his yard, calculating Trayvon Martin’s last steps with a tape measure and smartphone stop watch.

He is joined on the Internet by Dave Turner, an Illinois man who had his sons yell in the dark from a distance of 30 feet to see whether he could tell which one cried for help.

Both men are often guided by the work of “Tchoupi,” an engineer with a Ph.D. in physics who has spent countless hours making maps, analyzing witness statements and fleeting headlight patterns in surveillance videos to compute George Zimmerman’s moves the night he killed Trayvon.

The three are among a growing group of people on the Internet so fascinated by the mystery of the killing that captivated the nation that they are out to crack the case themselves. They listen to jailhouse calls, pore over witness statements, study evidentiary documents and measure walking speeds.
