SANFORD, Fla. -

The 7-Eleven clerk who last saw Trayvon Martin buying Skittles and an Arizona brand watermelon fruit juice testified in the George Zimmerman trial.

Andrew Gaugh was the second witness to be on the stand after testimony began June 24, 2013. He did not see the crime scene; he did not know that the teenager wearing a hooded sweatshirt was going to be killed.

Prosecutor Bernie de la Rionda played the surveillance video, which showed Trayvon making his last purchase.

An attorney asked Gaugh if Trayvon looked suspicious. Guagh said "no."
