Marchella Pierce weighed just 15 pounds and had marks on her hands and ankles when police discovered her body in her family's apartment.
The family was supposed to be monitored by ACS, and now the question is, how did the case fall thru the cracks?
"Somebody knew this was going on, and they didn't say anything," said Salvador Duplessis.
A bed affixed with pieces of twine and marks on her daughter's emaciated 15 pound body lead investigators to believe the 4 year-old was tied to the bed.
"To hear another mother did that just hurts, and we just hope that's not the case," said Lagrane Jefferson.
Hospitalized since her premature birth and nourished with a feeding tube, and having to breath with an oxygen tank, the sickly child came home in February.
ACS subcontracted supervision of the family to the Child Development Support Corporation in January. Its contract expired two months ago.
The nonprofit agency visited the family four to five times a month when it contract expired at the end of June. They recommend ACS keep the Pierce case open for continued supervision.
The city medical examiner's office says further tests are needed to determine the cause of death.
