ORLANDO -- Orange County confirmed Sunday they found Caylee Anthony’s hair in the trunk of her mother’s car.
The latest development in the case of the missing 3-year-old comes after other air sample testing showed a decomposing body was inside the car of Casey Anthony.
Orange County investigators joined the mounted search and recovery group Texas EquuSearch Sunday to look for Caylee.
Deputies sent up their helicopter, along with infrared equipment from EquuSearch.
About 150 volunteers also searched on the ground, in a wooded area near Orlando International Airport.
Deputies said they are focusing on areas they think might be fruitful, but admitted with results back from the Federal Bureau of Investigation lab, they are probably looking for a body.
Casey Anthony remains in the Orange County Jail after being rearrested Friday night on new charges not related to Caylee's disappearance. See previous story.
