Three more possible victims have come forward with accusations against an alleged serial rapist, Northampton County officials announced Monday.

District Attorney John Morganelli announced the arrest of David Martinez last week. He was charged with raping two teen girls at his home on Maple Street in Bethlehem.

A day after the arrest was announced, Morganelli said three more possible victims had stepped forward. The number of potential victims now stands at six, Morganelli said.

The investigation is ongoing, and more charges are expected, Morganelli said.
