BURNSVILLE (AP) - Authorities are investigating what prompted a shooting inside a discount store in Burnsville that left one person dead and another injured.

The shooting at the Dollar Tree store in a Burnsville shopping area happened over the noon hour Monday. One victim died Monday evening and the other was hospitalized in unknown condition. Both were males.
