Diego was with a group of 4 people. After making the entry into the U.S., they were taken by car to the point that they would start walking. They started walking for 1.5 days before Diego stopped because he could not walk any farther. The rest of the group had 6 hours left to go, and as they continued, they were eventually detained by Border Patrol who were using tracking dogs. The last time anyone heard from Diego was on May 31st, 2014 when he called his sister just after they had crossed. (Information retrieved from NamUs.gov)
