The San Antonio, Texas, Archdiocese called for unity after 46 migrants were found dead in a trailer, in what authorities are calling San Antonio’s largest mass casualty event. 

"We pray for the souls of the 46 people who died in such a cruel, inhuman manner this evening, and also keep in prayer the 16 survivors – 14 adults and four children – as well as their families and all of the first responders who assisted and saved lives and must now carry with them the memories of this scene of carnage," San Antonio Archbishop Gustavo Garcia-Siller said in a statement. 

"I urge all in the archdiocese to unite in solidarity, as these brothers and sisters are members of our family," he added. 

Authorities said Monday that 46 migrants were found dead inside and around an 18-wheeler’s trailer. The death toll later rose to at least 50, after more people found in the trailer were declared dead at a local hospital. More than a dozen others were hospitalized.
