Monet Robinson, 5, Killed In Hit And Run: Driver Looked Out At Victim, Then Fled, Witnesses Say (VIDEO)

Witnesses say the driver of a green four-door Pontiac Grand Am stopped to look out the window at the 5-year-old girl that was fatally struck by the vehicle before speeding away unidentified.

Monet Robinson, as identified by the Cook County Medical Examiner, contrasting a relative's identification of the girl as Monae Lucio, was hit by the green Pontiac on a busy street in her Lawndale neighborhood just before 8 p.m. Monday as she ran behind her sister, NBC Chicago reports.

The driver, described as a male believed to be in his 20s, looked out the window, according to witnesses, before speeding off.

The car sustained serious damage to the passenger side, according to police, the Chicago Sun-Times reports. Witnesses say the car slammed into Robinson and sent her flying into the air. She was taken to Mount Sinai Hospital in critical condition and pronounced dead there at 8:19 p.m.

"The little girl was running across the street here and the car was speeding up," one witness, who gave only her first name, Phedra, told the Chicago Tribune, adding, "She was running across the street to come over and play with the other kids. [The driver] stopped and looked out the window and kept going. ... I could do nothing but scream and cry."

Chicago police are investigating.
