McAllen Border Patrol agents together with the Hidalgo County constables office identified a stash house in Mission.
Agents conducting surveillance at the home noticed the driver they tried to approach leave from the home.
Inside, they found 19 undocumented immigrants, and just yesterday, a welfare check at a home in Donna, led to the discovery of another 21 undocumented immigrants.
This includes men, women, and children from Central America and Mexico.
