Police are searching for a vehicle they say drove away from a crash that killed an infant and four others and left a woman in critical condition just outside Atlanta.

Fulton County Police detective Melissa Parker says the crash happened around 1:45 p.m. Sunday when a BMW and a Mercedes hit each other, sending the Mercedes across the median into oncoming traffic.

Parker says the Mercedes struck a Volkswagen and grazed another vehicle.

Names of the five killed and were not immediately released. Police are looking for the BMW.
