This episode of cold case deals with an infant's death which was listed as Sudden Infant Death Syndrom. Present day they find that it's not SIDS..The box that has evidence is dated Nov. of '82. when present day detectives investigate they question the mother. She said the night the baby died it was snowing. She felt it was a sign, because it was snowing the day she was born. I know it's possible to have snow in Nov. in Philadelphia, but the baby is approx. 3 - 4 mos. old. that means she was born in the summer. It does not snow in Philadelphia in the summer. I'm from New England and it doesn't snow in the summer. so I doubt it would snow in PA
