A 9-year-old boy who helped save the lives of a 3-year-old girl and her grandfather after finding them floating face down in a San Jose pool on Monday is the city’s latest hero.

“He just feels very proud of himself,” San Jose fire Capt. Mary Gutierrez said of Isheen Singh.

“He said, ‘I’m very proud that I was able to save her,’” Gutierrez said.

Isheen was among 10 to 12 people who had been hanging out by the pool at an apartment complex at 355 South Kiely Blvd. around 1 p.m. when he noticed two bodies floating in the deep end.

He dove in and pushed the little girl to the side of the pool while other residents helped pull her out. Meanwhile, a woman dove in and pushed the man to the side of the pool, and he was also pulled from the water, Gutierrez said.

Bystanders administered chest compressions on both the man and the little girl until firefighters arrived.

Firefighters arrived within four minutes and found the man and child lying by the side of the pool. They were breathing but were unconscious and unresponsive, she said.

As of Monday evening, the little girl was doing well but her grandfather was in serious condition, Gutierrez said.

She said it is likely the girl was underwater for about three minutes that and her grandfather had been underwater for anywhere from three to five minutes.

Last week, a man came to the rescue of a 6-year-old girl and her father at another housing complex pool in San Jose. He found both at the bottom of the pool, pulled them out and helped resuscitate them.
