Authorities say a 45-year-old mother in northern New Jersey died of cardiac arrest when she tried to break up a domestic dispute between her son and his girlfriend.

The pair face charges stemming from the death of Ana Rojas-Jovel.

The Bergen County Prosecutor's Office says 28-year-old Juan Martinez Rojas and 25-year-old Claudia Hernandez Soriano started fighting in front of a child after they returned to their Waldwick home from a party early Monday.

Authorities say Rojas-Jovel tried to intervene and was assaulted by Hernandez Soriano.

Rojas-Jovel suffered a cardiac event and died.

Hernandez Soriano is charged with reckless manslaughter.

Martinez Rojas is charged with child endangerment.

They're scheduled to make an initial court appearance on Thursday.
