Locklear was found with cement cinder blocks tied to her body.
Her boyfriend Je’Michael Malloy, 17, confessed to killing Locklear and has been charged with second degree murder.
Locklear and Malloy got into an argument that turned violent, he strangled her and stuffed a sock in her mouth, according to ABC 11 News.
