The teenage brothers charged with killing a 12-year-old girl in New Jersey appear to have left behind a trail of evidence around their home and online.

Police said 17 year-old Dante Robinson and 15 year-old Justin Robinson lured Autumn Pasquale to their house on Saturday. According to  police, the brothers then killed Pasquale by strangling her.

Pasquale's body was found stuffed in a recycling container Monday night just blocks from her home after a two-day search of Clayton.

Authorities say several clues led them to the teens.

Their own mother called police because she was concerned about a Facebook posting by one of them.

The girl's body was found in a recycling bin next to the family's home. Her bike was in the house.

Authorities have not disclosed the boys' names because they're charged as juveniles. A prosecutor says he may seek to have the case moved to adult court.

Pasquale would have turned 13 next Monday.
