Police say three people are dead and a fourth is injured in a shooting at a condominium building in Louisville, Ky.

Asked if there was a suspect, police spokesman Dwight Mitchell says officers believe everyone involved was accounted for. He said the shootings took place inside an apartment but would not say whether there were other people inside at the time.

Mitchell also wouldn't indicate the ages of the victims and said the investigation was just beginning.

The shooting was reported shortly before 4:30 p.m. EDT.
