We found these pictures of Alex on the internet. One was from a blog that a teacher at the CCM(MTC) posted. The other was from an article in the LDS church news about the new MTC. CCM is MTC in spanish...Centro de Capacitacion Misional.
Alex is in the back on the right side. This was at the Mexico City airport when they arrived.
Alex is on the back row, 7th from the right. He isn't wearing his glasses.
