The cause of death was "homicidal asphyxiation", a method that apparently left virtually no marks on the body.
Drugs, alcohol and burning were ruled out as possible causes of death.
A high school freshman at the Academy for Young Writers in Williamsburg, Shaniesha lived with her family on Avenue I in East Flatbush.
She had been reported as a runaway two days before her body was discovered -- several miles from her home.
Some of her partially-burned clothing was found in nearby bushes.
No suspect has been named.
