At around 5:00 p.m. Wilmington police were called to St. Francis Hospital for a report of a child shot.
While police were responding to the hospital, officers received additional calls for another person shot along the 1500 block of West 4th Street.
Upon arrival, officers located a teenage male lying in an alleyway suffering from a gunshot wound to the chest.
The teen was transported by ambulance to Christiana Hospital where he was later pronounced dead.
Meanwhile, the boy, said to be 10-12 years old, was transferred by ambulance to A. I. DuPont Children's Hospital for treatment.
Officials say he suffered a stomach wound and is currently listed in critical condition.
A relative of the victims, Unity Watson said the two victims were cousins and the boy who survived is her brother.
"He was out with his friends. I guess he was at the wrong place at the wrong time," said Watson.
Police say a second boy involved in this incident suffered a minor injury unrelated to the shooting. He too was taken to DuPont.
