Kalamazoo Police have a person of interest in custody in a fatal shooting that left one 13 year old boy dead, Monday evening. Michael Day was found with a gunshot wound to his upper body, at around 7 pm in Kalamazoo’s Edison neighborhood. He was rushed to the hospital but was pronounced dead a short time later. Authorities have an 18-year-old man in custody. His name has not been released, but investigators say they believe the shooting may have stemmed from an argument earlier in the day.  The victim had recently been released from the hospital after having been shot a few months ago.
