A young child died after going into cardiac arrest in Boston’s Mattapan neighborhood on Tuesday, police said Wednesday, as they investigated what happened. Genesis Parris is mourning the sudden loss of her 4-year-old son, Sadoni. She said a man she knows took her kids to day care on Tuesday, while she went to the hospital with early contractions. “I trusted him to pick them up, bring them home and for me to sit in the hospital,” said Parris. |
