One man is in custody after officers responded Wednesday morning to a report of shots fired on Milwaukee’s north side.
Officers were called to the scene near Capitol and Estabrook Parkway just after 7:30 a.m.
The Milwaukee County Sheriff’s Department says investigators found two bunkers on the west bank of the Milwaukee River that they believe was used by the suspect.
Officers recovered firearms and ammunition from one of the shelters.
It remains an active investigation.
