Authorities say a 45-year-old North Jersey mother 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 said 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.
Rojas-Jovel tried to intervene and was assaulted by Hernandez Soriano, according to authorities.
Rojas-Jovel suffered a cardiac event and died.
Hernandez Soriano was charged with reckless manslaughter. Martinez Rojas was charged with child endangerment.
They're scheduled to make an initial court appearance on Thursday.
