A family left behind their son’s new wheelchair when a mass shooter began opening fire in an El Paso Walmart — and it was used to help an elderly man escape the nighmarish scene, according to new reports.

The family of the boy, only identified as Angel, traveled 12 hours last Friday from Durango, Mexico, to pick up an age-appropriate wheelchair at the local BEK Medical store.

The next day, Angel and his family stopped at the McDonald’s inside the Walmart, Dora Williams, the president of BEK Medical, told local outlet KTSM.

When shots started ringing out, they were so scared that they carried Angel out of the store, leaving the chair behind, according to the report.

“They didn’t know where to go, so they came to us,” Williams told the outlet. “Our employees kind of helped them out. They wanted to go home. We wanted them to stay over to see if we could find the chair, but their kids were extremely nervous, so they just wanted to drive back home.”

Meanwhile, Jose Luis Gutierrez, 72, was shopping for groceries at the Walmart when accused gunman Patrick Crusius first started his shooting rampage, the shopper’s sister-in-law, Lorena Pacheco, told local outlet KVIA.

Gutierrez was not hurt, but went into a state of shock, Pacheco told the outlet.

A police officer put Gutierrez in the wheelchair, assuming it was his because he normally walks with a cane, and wheeled him out, Pacheco said.

But when Gutierrez regained his composure, he told his sister-in-law he remembered that a parent had grabbed their child out of the wheelchair and run away as the shooting began.

He didn’t recognize the parent or the child, and had no idea whether they survived, according to the report.

Ultimately, Pacheco made contact with BEK Medical — and Williams said the company has found someone to bring the wheelchair back to Angel and his family.

“Praise God, it’s a blessing,” Williams told KVIA. “We talked to the family and they are so excited.”
