Manjeet Singh was standing on the bank when he saw the kids struggling and decided to jump in at the bridge to save them.

“He didn’t know them, but just saw them needing help so he jumped in,” said Ediger.

Meanwhile, the search for the good Samaritan continued.

After 40 minutes, Singh was found underwater and unresponsive. He was pulled out and transported to the hospital where he was pronounced dead, Ediger said.
