Milwaukee police say the persons of interest in the mass shooting where six people were killed last month are no longer being held.
Officers found the six bodies as they were making a welfare check on the city’s north side on January 23rd.
Milwaukee police said four persons of interest were in custody last week – but those four have now been released and no one has been charged.
Department records reveal officers had been called to the location 18 times in the last three years.
The victims were all shot to death.
