Prosecutors filed new charges against a man whose son was last seen in July 2011.
Calvin Melvin, Jr., was originally charged with three counts of providing false information to a law enforcement officer. Prosecutors filed two charges of child neglect against Melvin on Friday.
His son, Dontrell, was last seen when the boy was six months old. Melvin and the boy's mother, Brittney Sierra, are both charged in connection with their son's disappearance.
Sierra is charged with child neglect resulting in bodily harm.
A Broward Sheriff's Office deputy discovered the boy was missing while investigating an unrelated child neglect case on Jan. 9.
Police say Melvin and Sierra blamed each other for the child's disappearance, but both told detectives where to find the child. The remains were found buried in the back yard of a home the couple rented in Hallandale Beach.
According to the Hallandale Beach Police Department, a University of North Texas DNA analysis report found "genetic data are approximately 31.2 trillion times more likely to be observed under the scenario that the unidentified remains originated from a biological child of Brittney J. Sierra and Calvin Melvin Jr. as opposed to the unidentified remains originating from an unrelated individual from any of the three major U.S. population groups."
The remains police found had blunt trauma injuries, according to Hallandale Beach police reports. But the reports indicate the injuries were caused by police officers during the recovery process.
Melvin is scheduled to be arraigned April 5.
