Bystander Effect Facts

When a speeding GMC truck crashed through a bridge fence and plunged upside down into Utah's Jordan River in 2014, Leo Montoya Jr. was the first person to jump in - then shouted at frozen bystanders until more than a dozen strangers waded in beside him. Together they physically flipped the submerged vehicle upright, held one boy's head above water, and got all three trapped teenagers out alive.

On Labor Day 2021, five men from a halfway house spotted a burning car on Interstate 8 in Lakeside, California - and pulled over while everyone else drove past. Ken and Joan Williamson, ages 92 and 90, had been rear-ended and were trapped inside as the flames spread. The car exploded during the rescue. Every single one of them stayed.
