"The brothers are ages 15- and 17-years-old and both are in police custody at the present time," said Gloucester County Prosecutor Sean Dalton. "The 15-year-old has also been charged with one count of luring."
Some 200 law enforcement members had been searching for Autumn Pasquale, the Gloucester County Prosecutor's Office said, since Saturday when the 12-year-old went missing from her New Jersey home.
Also a Facebook page had been created to help in the search for her.
The family was notified on Monday.
"This is a very sad day for the Pasquale family," said Gloucester County Prosecutor Sean F. Dalton."Our hearts go out to the family."
Pasquale was last seen Saturday night when she rode her bike from her home in the town of Clayton, New Jersey.
She was set to turn 13 next week.
