An 88-year-old school crossing guard in the US has died a heroic death after saving two schoolboys from an out-of-control driver.
Kansas man Bob Nill was patrolling outside Christ the King Catholic School when he saw a black sedan speeding towards the crossing, local media reported.
Witnesses said he pushed two boys who had stepped off the curb out of the way. According to The Washington Post, the driver hit Nill where he stood.
Principal Cathy Fithian said she found his stop sign 6m from the crossing.
"I know he had it in his hand. It was right in the centre of the road."
Nill was rushed to the hospital, but died of his injuries.
One of Nill's three sons, Bart, told The Washington Post his dad felt lonely in retirement after recently losing his wife.
His family was overjoyed when Bob took the job as a crossing guard.
"It was the neatest thing in the world," Bart said. "It got him back on a schedule again, he got to sleep when he was supposed to - but it also allowed him to spend time with children again, because Dad, he just loved kids. You could sense that."
After the incident, the school prayed for the man and told parents to "know that Mr Nill is a hero".
