A Trenton man was at large Monday after shooting multiple family members during an argument at his home very early Sunday morning, police said.

A police spokesman said the man and his wife, 31, were having a verbal argument in their home on Maple Avenue in Trenton around 2:30 a.m.

When the conversation began to get heated, police said, the woman's mother and brother tried to intervene.

The husband pulled out a handgun and fired six rounds, striking his wife, mother-in-law, 57, and brother-in-law, 25, police said.

He then fled the scene.

Police did not make public any names of the victims, or the husband, because the incident stemmed from a domestic violence incident.

Authorities are unsure of the husband's whereabouts, and an investigation into the shooting is ongoing.

Emergency responders took the three victims to Capital Health Regional Medical Center for treatment. The wife is still being treated for her injuries, but her mother has since been discharged, police said Monday.

The woman's brother is currently in the intensive care unit for treatment of a gunshot wound to the chest.
