El Paso shooting suspect Patrick Crusius once tried to recruit a friend to a local white supremacy group, according to a new report.

The parents of the pal said their son and Crusius became friendly while attending Plano Senior High School.

“When [our son] referenced Patrick, it was in a glorified manner,” the dad told local station WFAA.

In 2017, Crusius tried to recruit the other teen into the small white supremacy group — prompting the parents to alert the police.

“I blew a gasket. ‘You know this isn’t right. We’ve taught you better than this,’ ” the mother said she told her son.

A report was filed with the Allen Police Department over white supremacy activity but did not mention Crusius, police said. The parents also claimed they notified the FBI.

The school district confirmed the boys attended the school at the same time.

The parents, who weren’t identified in the news report, said they have a strained relationship with their son but spoke to him briefly on Saturday — the day Crusius allegedly slaughtered 22 people inside a Walmart.

“It was more like fireworks were going off. It just hit a chord,” the father said of watching news coverage of the shooting and realizing Crusius was being accused of being the gunman.
