NORTH MIAMI (CBS4) — North Miami Police confirm the gunman responsible for an hours long standoff has taken his own life.

SWAT teams stormed the apartment at 132nd Street and NE 6th Avenue and found the gunman with a self-inflicted gunshot wound.

CBS4′s David Sutta reports that just before 5 p.m. a gunman began shooting and barricaded himself inside the building, blocks were surrounded by police cars and emergency vehicles.

It was originally reported that the violence began as a failed car-jacking, but North Miami Mayor Andre Pierre told CBS4′s David Sutta that it was actually a domestic violence incident.

Pierre says a man shot his girlfriend, and a two year old boy was caught in the crossfire. Both were transported to the hospital.

Firefighters were attending to a third victim when they also came under fire, According the MDPD spokesman Eric Baum.

The rescue crew then moved into a nearby apartment to escape the gunfire. Officials say they used furniture to block to door and continue treating the victim.

The SWAT team was able to shield them as they came out of the apartment and to a waiting ambulance.

The gunman is reportedly holed up inside an apartment, and his brother is there working to get him to surrender to police.

Chopper 4 was over the scene as the situation was developing and was able to capture video of police as they ran into the building and pulled out one person on a backboard and lead several children to safety.

Mayor Pierre says North Miami High was also on a modified lockdown while the incident played out.
