Eighteen-year-old Shaniqua Pierre is from Deptford.
The bodies of 23-year-old Michael Hawkins of Mount Holly and 18-year-old Muriah Ashley Huff of Cinnaminson were found buried in the yard of a Camden home on Feb. 26.
Nine people are charged with at least one murder in the case.
All of them are teenagers and most of them lived in the suburbs.
Authorities say they want to try the four minors - including a 14-year-old girl - as adults.
