A Houston resident captured a memorable moment  as he was trying to get help during Hurricane Harvey.

Brian Roberson II was stuck on Texas State Highway 288 when he came across a man on top of submerged cars.

The man told Roberson he was a pastor and wanted to help to make sure no one was in those stranded vehicles.

"It was such a powerful visual that shows how we can all do something to look out for each other," Roberson said.

The pictures Roberson took show the pastor in chest-deep water as he tries to check for victims.

Roberson's aunt, Tera Stidum, said in a Facebook post that Roberson didn't get the pastor's name, and only remembers him saying his church is in the Yellowstone area, and starts with the word "Mt."

"If you have ANY clue who this man could be, please hit me up," Stidum said.
