BROOKLYN - Charges have been dropped against two former New York City case workers in connection with the death of a 4-year-old Brooklyn girl.

Damon Bell and Chereece Adams were charged in 2011 with criminally negligent homicide after Marchella Brett-Pierce died in Sept. 2010, weighing just 18 pounds.

The case workers had pleaded guilty to misdemeanor charges under a plea deal.

The child's mother, Carlotta Brett-Pierce, was sentenced to 32 years to life in prison, and the girl's grandmother, Loretta Brett, was convicted of manslaughter.
