In Jamaica, Queens, a wall gave way in a home, sending water rushing in, killing two, a 43-year-old woman and a 22-year-old man, around 11 p.m. Wednesday. Officials believe they are mother and son, WPIX reported. The man was pronounced dead at the home. The woman was taken to a hospital where she was declared dead.

In that instance, the street that runs past the home floods frequently and construction had started to repair the issues.

“The purpose of the construction was to make sure this doesn’t happen,” a neighbor who was not identified told WABC. “They took the whole block apart, but obviously city planning didn’t make it work.”
