Weslaco Police *** said detectives are still investigating how the teen ended up in the Valley.
"The next step now is just waiting and for further verification and to see what arrangements can be made with possibly a state agency to get him shelter pending the arrival of family members so that he can be released to their custody and we can get him back home,
Action 4 News contacted Border Patrol officials and asked why the agents dropped off this special needs teen at a bus stop instead of trying to find his origins or contacting police.
They released the following statement:
"U.S. Border Patrol agents from the Rio Grande Valley Sector encountered this individual near the Rio Grande and developed reasonable suspicion that he may be in the country without documentation. The subject was taken to the Weslaco Border Patrol Station for further investigation. Agents were unable to identify him or determine his citizenship, and had no legal basis to detain this individual any further. Agents made contact with multiple local law enforcement agencies that declined to take custody of the individual. Due to the fact that we do not have adequate facilities or authority to house him, he was transported to a public area and released."
