BUFFALO, NY - Buffalo Police are investigating an accident that killed a seven-month-old baby girl Sunday night.

The accident happened on Moselle Street around 9:45 p.m.

"We heard two loud sounds, boom, boom and it was real loud we jumped up," said Derek Williams, a neighbor.

Accident investigators say a vehicle was traveling south on Moselle when it struck an infant in a stroller and two other people. The two other victims include the baby's mother and a cousin.

Police investigators say an off-duty Buffalo fireman witnessed the accident and stop to render aid, by administering CPR on the infant, who family have identified as Nyree Anderson.

"He's a witness and he did stop and render aid to the women," said Lt. Thomas Leatherbarrow of Buffalo Police.

Nyree was taken to ECMC where she was declared deceased. Police say she died of blunt force trauma and other injuries. The mother of the baby refused treatment. The other woman was taken to the hospital -- she is expected to be ok.

Police say the driver, a 44-year-old male from Buffalo, was on his way home from a friend's house. No charges have been filed at this time. Police are awaiting toxicology test results from the driver.
