The medical examiner determined a cause and manner of a baby girl's death at a Bronx day care.

River Wilson, 1, died in an accidental drowning, the medical examiner says.

Police found baby River in an above-ground pool at Ana's Butterfly Garden in the Bronx on Aug. 1.

River was taken to Montefiore Hospital-Einstein, where she was pronounced dead.

Earlier this month, River's family announced their plans to file a lawsuit against Ana's Butterfly Garden.

News 12 reached out to the Bronx District Attorney's Office, which say it is still evaluating the evidence in River's death.
