Hidalgo County sheriff's deputies located 84 migrants on Thursday afternoon as they unloaded from a tractor trailer just 12 miles from the U.S.-Mexico border in south Texas. 

A concerned citizen originally reported the tractor trailer near a residence about 15 miles east of downtown McAllen. 

Sheriff's deputies and Border Patrol responded to the scene and took the migrants into custody. Pictures released by Hidalgo County Sheriff Eddie Guerra show dozens of migrants on the ground in what appears to be a residential area.

A TikTok video was posted late on Wednesday evening, seeking "someone who can drive an 18 wheeler right now" from McAllen to Houston for $70,000. 

The Texas Department of Public Safety verified that the video is authentic and related to the migrants who were located in Hidalgo County on Thursday.

Texas DPS spokesman Christopher Olivarez said that law enforcement has seen an uptick in recruitment videos on social media sites since last year. 

"That is why we are experiencing an increase in human smuggling events along the border," Olivarez told Fox News Digital. "Many individuals from larger metropolitan areas such as Austin, Houston, Dallas, San Antonio, and even out of state are being recruited as drivers through social media platforms to smuggle illegal immigrants."

Cartels have turned to social media in other states as well. Sen. Kyrsten Sinema, D-Ariz., introduced a bill last week that would crack down on cartels' use of various platforms to recruit people for human trafficking operations. 

"Cartels recruit teenage Arizonans to support smuggling and trafficking near our border – luring them into dangerous and illegal activities for easy cash that puts their lives and others at serious risk," Sinema said in a statement. 

Customs and Border Protection did not immediately respond to requests for comment about the conditions of the migrants or any arrests that were made on Thursday.
