A New Jersey mom ratted out her teen sons for the murder of a 12-year-old girl after reading a Facebook posting hinting that one of them wanted to go on the lam, law-enforcement sources told The Post.

Justin Davidson’s mom saw his message “Might be moving :(” on Sunday and became suspicious.

She tipped cops that he might have been involved in the disappearance of their neighbor, Autumn Pasquale, in Clayton, NJ, the sources said.

Autumn was allegedly lured to meet Justin, 15, and his brother Dante Robinson, 17, at their home Saturday because they wanted parts from her beloved BMX bike.
