BURLINGTON CITY - A Burlington County woman accused of grabbing a 5-year-old girl on a light rail platform and throwing her into the path of an oncoming train has been indicted on an attempted murder charge, authorities said.

Autumn N. Matacchiera, 20, of Hainesport, did not know the girl or her mother, authorities said. During two phone calls from a psychiatric hospital following her arrest, Matacchiera told the Courier-Post she was trying to "sacrifice" the girl.

Matacchiera has remained hospitalized since her arrest, according to the Burlington County Prosecutor's Office.

After Matacchiera threw the 5-year-old onto the train tracks in Burlington City on Jan. 27, police officers jumped to her rescue and signaled the approaching train to stop, authorities said.

The mother's boyfriend pulled the girl from the tracks. The 5-year-old suffered bruises and a cut to her face, authorities said.

The police officers were in the area of the West Broad Street station after being alerted by an NJ Transit bus driver about suspicious activity.

An arraignment for Matacchiera on the attempted murder charge has not yet been scheduled.
