Firefighters were forced to go through windows to battle an early morning fire at the Van Dyke Houses and to rescue 4-year-old Rolando Rich and his 3-year-old sister Dasani. The mother left the toddlers with their older siblings, ages 15 and 11, while she went to the store. The older children got out. The 15-year-old tried to help the toddlers but a wall collapsed. Both children are in serious condition at Brookdale University Hospital. The little boy — who has leukemia — is on life support.
