Bail was set at $75,000 for Gibson and $40,000 for the other two defendants, who were being held at the county jail. They did not enter pleas, and all three requested public defenders. All three wore belt cuffs in court.
Officials used DNA to identify the remains, including a skull and jawbone, which were discovered by a hunter in tall grass. LeMieux said they were partly burned. The remains also showed evidence of scarring and two fractured ribs that had healed, he said.
Acting Monmouth County Prosecutor Christopher Gramiccioni said a tip received within the last two months allowed authorities to identify the girl.
The case got attention in 2009 when detectives appeared on the TV show "America's Most Wanted" to seek help in solving the case.
Prior to the break in the case, investigators had estimated the child was a girl between the ages of 5 and 9 and had died between 2001 and 2004.
