Police are looking for two more people to talk with regarding the death of a 15-year-old Missouri girl whose weighted-down body was found in Truman Lake.

Sheriff Mike Rackley says a 24-year-old woman and 39-year-old man are considered "persons of interest" in the disappearance and death of Khighla Parks. 

The woman is listed as a Facebook friend of 47-year-old Anthony Balbirnie, who has been charged in for now only with abandoning a corpse. 

Khighla was last seen Sept. 20. An anonymous female told investigators she saw Balbirnie wrap Khighla's body and put it in his car's trunk the next day. Fishermen found her body in Truman lake around Warsaw about a week later.
