Former Nickelodeon child star Kianna Underwood killed in New York hit-and-run

Former Nickelodeon child star Kianna Underwood was identified as the victim of a horrific hit-and-run that left her dead after she was dragged across two Brooklyn blocks early Friday morning.

Law enforcement sources tell TMZ that the 33-year-old woman – who appeared on the 2005 series “All That” – suffered severe trauma to her head and torso… when a gray vehicle, driven by an unknown suspect, was traveling west on Pitkin Avenue and struck her as she crossed the street at Pitkin and Mother Gaston Blvd.

We’re told Kianna was left motionless in the roadway after being dragged under the car for nearly two blocks.

Sources tell TMZ that the NYPD received a 911 call around 6:49 a.m. Friday — and when emergency responders arrived, Kianna was pronounced dead at the scene. No arrests have been made at this time.

Kianna was a talented child actress who also starred in Nickelodeon’s “Little Bill.”

She was 33 years old.
