Just after 2 a.m., police responded to a  disturbance with shots fired at the Horizons East Apartment complex located in the 500 block of North Rock Road, according to officer Kevin Wheeler.

Upon arrival, officers found a 20-year-old man who was shot and was unresponsive in the parking lot.   Officers rendered aid until medical personnel arrived, who continued life-saving measures. The man was shortly after pronounced deceased.

The victim’s name is being withheld pending notification of next of kin.  Two of the three other  victims include a 21 year-old-male and a 22-year-old male.  They were transported to a local hospital where they were treated and released for non-life threatening injuries.  A 19-year-old female was also transported by private vehicle to a local hospital with a gunshot wound.  Her injury is considered to be serious, but she is expected to survive.
