A group of Laredo Police Department officers out serving a warrant in south Laredo on Friday morning inadvertently stumbled upon a stash house packed with 69 undocumented immigrants.

Officers were out to serve a two-day-old burglary of a vehicle and theft of property warrant to a 20-year-old suspect in the 4500 block of Corrada Avenue. When they knocked on the door, officers heard what sounded like a stampede of people inside, according Investigator Joe E. Baeza, LPD spokesperson. An officer looked through a window, saw a huge group of people, and found probable cause to enter the house.
