A Brooklyn native is among the five people killed in a deadly crash on the Pennsylvania Turnpike.

Jaremy Vasquez, 9, was killed in the chain-reaction crash involving a bus, three tractor-trailers and a passenger car.

The bus was traveling from New York to Ohio when it crashed. The NTSB is looking into the cause of the crash, but is warning people the investigation will take some time.

“Over the next several months, we will be collecting additional information, everything from the history of the driver, history of the company, last inspection, there'll be toxicology information from the driver, so that takes time," says Jennifer Homendy, a board member with the NTSB.

A 35-year-old woman from the Bronx was also killed in the crash.

At this point officials say it's too early to determine if weather was a factor in the crash.
