As soon as he heard about the tragedy unfolding in San Antonio, wheredozens of people were found dead in a tractor-traileron Monday, a local Archbishop began visiting survivors to make sure they knew people were supporting them.

Gustavo García-Siller, the archbishop of the diocese of San Antonio, toldNBC Newsthat he visited nine hospitals from Monday evening into Tuesday, but that many of the survivors he saw were intubated and not communicative.

​"That trailer was abandoned. The bottom line is that immigrants were abandoned. People. People," he told the outlet, the emotion audible in his voice.

“This is the experience of many immigrants coming to the States even if they cross,” he added.

As of Wednesday afternoon, the death toll increased to 53, while 11 individuals remain hospitalized, a spokesperson for U. S. Immigration and Customs Enforcement tells PEOPLE.

One woman, who opened her eyes just as he was about to leave, was able to tell García-Siller that she was from Guatemala, according to NBC News.

“I said, ‘You are alive and we are grateful to God and we hope to see you improving constantly,'” he recalled telling her.

During another visit, he was able to speak with a 6-year-old girl, who told him her name and that she is from Guatemala.

“I said something like, ‘You are a really beautiful person,’ and she smiled,” he told NBC News. “I said, ‘Smile often. People around you need to see you smile. In these difficult times your smile is a way to communicate and you can do some good for us.'”
