Multiple bodies were discovered inside a Union Pacific cargo train in Laredo, Texas, on Sunday afternoon, sparking a major investigation by local authorities.
According to the Laredo Police Department, officers responded shortly after 2:30 p.m. local time near mile marker 13, close to 12100 Jim Young Way, an area near the Union Pacific rail yard in north Laredo.
Police confirmed that multiple bodies were found inside the train but did not immediately release the exact number of victims or identify the deceased.
As of Sunday night, investigators had not announced the identities of the deceased or released details regarding possible survivors.
Authorities have not confirmed whether the train originated in Mexico, or the cause of death, how long the bodies may have been inside the railcar, or whether foul play is suspected.
Investigations are ongoing, with officials working alongside federal authorities and medical examiners to determine the circumstances surrounding the deaths.
The discovery came during a period of intense heat in South Texas, with temperatures in Laredo climbing to nearly 95 degrees Fahrenheit on Sunday.
Authorities have not yet confirmed whether heat exposure may have contributed to the deaths.
The location of the discovery has given rise to speculation that the individuals may have been migrants attempting to cross the border through freight transportation routes frequently used by smugglers.
