Univision News received more than 150 testimonies of Latinos who traveled by tractor-trailer to get to the U.S. from their countries of origin. Here are some of their memories.

José de Jesús Martínez tells Univision his son is suffering the effects of having been trapped in the ill-fated tractor-trailer: days later, he can barely speak a few words. The father's anguish is only made worse by fears of detention and deportation.

The footage shows a man wearing a badge, apparently from the local sheriff’s department, and claims to be bail bonds agent. A lawyer then rebukes and questions his authority.

Univision News went out with an ICE team searching for criminals in Los Angeles. So far this fiscal year, the team has arrested more than 5,481 undocumented immigrants.

One of the nine Immigration and Customs Enforcement fugitive detention teams in Los Angeles allowed Univision News to follow along on July 11, 2017, to witness officers' day-to-day operations in the San Fernando Valley. By the end of the day, agents had detained three Mexicans with criminal records, which added to the more than 2,200 arrests since January in this region.

A reader tells Univision she was verbally abused at a hospital in the midst of an illness. The woman, an undocumented immigrant, says she's never felt more fearful during the more than 20 years she's lived in the United States. A lawyer responds: "Whether or not you're undocumented is not relevant to your care."
