TOMS RIVER - The juvenile charged in last week’s murder of a 44-year-old woman at a medical office park on Route 37 West is the victim’s teenage son, according to multiple sources familiar with the investigation.

Margarita Diaz of Manchester was found in Deer Chase Professional Park at 8:42 p.m. on Aug. 7 after police went there for a report of an assault and found Diaz unresponsive. First responders tried to revive Diaz, but she was later pronounced dead at nearby Community Medical Center, which is within view of the scene.

Diaz’s son — who is 17 — was charged as a juvenile in the murder of his mother, as well as unlawful possession of a weapon, possession of a knife for an unlawful purpose and endangering the welfare of another child.

He is being held at the Ocean County Juvenile Detention Center in Toms River.

The family lived in a modest, ranch-style house on Northampton Boulevard in the Pine Lake Park section of Manchester, residing with at least one other family in the home.

A young man who answered the door when a reporter visited referred all questions about Diaz to his father, who was not at home, but said he was not related to the victim.

Public details about the circumstances of the murder have been limited because of the criminal defendant’s status as a juvenile.

Bryan Huntenburg, a spokesman for the Ocean County Prosecutor’s Office, said it could not confirm nor deny any specific information about the suspect because of New Jersey privacy laws that protect juveniles charged with crimes.
