LATEST UPDATE: Gigi Woltz says it was the toughest thing she's had to do in her 16 years as a nurse when she ran out onto the field to give care to Issaiah Abrego, who had just collapsed on the sidelines.
Abrego was like a son to her.
Woltz tried to revive Abrego, giving him CPR and chest compressions.
"Right as the paramedics got there, I actually did back out because it became too much for me," she said.
A viewing was held Friday evening, and dozens of people showed up to pay their respects.
The night before, hundreds came to a candlelight vigil at the football field where Abrego fell.
UPDATE: A vigil will be held for Issaiah Abrego at Ed Fountain Park Thursday at 8:30 p.m.
LAS VEGAS (KTNV) -- A teenage football player collapsed and died on the sidelines during a game Monday night.
Issaiah Abrego was 14.
His parents, German and Veronica, say they were talking to him on the field at Ed Fountain Park near Vegas Drive and Decatur Boulevard when moments later, he fell.
"No one could believe what was happening. I still can't believe what's happening," Veronica said.
They say Issaiah's death is heart-related although he had no known history of issues.
