ROBSTOWN, Texas — The City of Robstown has brought in grief counselors for their first responders after Wednesday's tragic accident that claimed the lives of six men, all believed to be undocumented immigrants.

As of Thursday, five others were reportedly still in the hospital.

Six people were confirmed dead and seven others were taken to area hospitals with injuries. Authorities said the individuals were from Central America and Mexico.

Officials in Robstown said first responders are going through grief counseling after seeing such a horrible scene.

Psychiatric Nurse Jessica Wilson said even our heroes are affected by trauma.

"It can affect everyone a different way but sometimes the reactions are delayed," Wilson said.

Wilson said it can take nearly 90 days for the average person to process trauma, but for people like first responders who don't have time to react, the effects can lead to post-traumatic stress disorder.

"Nightmares, intrusive thoughts, having flashbacks of what happened, avoiding things," Wilson said. "We would then consider, is this post-traumatic stress disorder? In which case you'd really want to go seek some help and see if there's anything we can do to get you feeling better."

The crash in Robstown happened not even a year after a shooting that killed five people. Wilson said it helps to have grief counsellors available as soon as possible, because even our heroes need time to grieve.

"They're there for everybody, to take care of us all, and they don't want to be weak or maybe feel like they're not handling it well, but seeking help doesn't mean you're not handling it," Wilson said. "It's a little push. A little hug, and everybody deserves a hug."

3News is still working to confirm the identities of the victims involved in the crash, where they were headed, and if they had family here in Texas. We'll keep you updated as more information becomes available.
