HOBOKEN - A law enforcement official says Connecticut shooting suspect Adam Lanza's older brother, 24-year-old Ryan Lanza, of Hoboken, N.J., is being questioned by police.
An earlier report from a law enforcement official mistakenly transposed the brothers' first names.
Officials spoke on the condition of anonymity because they were not authorized to speak on the record about the developing criminal investigation.
Witnesses also confirm that an unknown man was taken into custody outside of Ryan Lanza's building.
Officials say Adam Lanza is dead from a self-inflicted gunshot wound.
