FORT LAUDERDALE, Fla. -

A woman whose son was found buried in the back yard of a Hallandale Beach home she rented with the boy's father has given birth.

Brittney Sierra, who returned to jail shortly after she was released last week, gave birth Wednesday. The Department of Children and Families wouldn't say whether what sex the baby was or whether it was healthy.

"The baby has been born. DCF has involvement with this family. Nothing further will be released," said DCF spokeswoman Paige Patterson-Hughes.

A woman volunteered to house Sierra, 22, so she could give birth but later changed her mind.

The body of Sierra's son, Dontrell Melvin, was found Jan. 11. The infant was last seen alive 18 months before.

The Broward Medical Examiner ruled he likely died when he was 6 months old. Sierra is charged with two counts of child neglect. The boy's father, Calvin Melvin Jr., is charged with three counts of providing false information to a law enforcement officer and two counts of child neglect.

A Broward Sheriff's Office deputy discovered the boy was missing while investigating an unrelated child neglect case on Jan. 9.
