What was supposed to be a 21st birthday celebration turned tragic when an uninvited guest opened fire, killing four people and injuring three others, police in Kentucky say.

Several partygoers called Florence police shortly before 3 a.m. Saturday regarding an active shooter inside a home on Ridgecrest Drive.

“When they arrived they still heard shots being fired,” Chief Jeff Mallery told reporters during a press conference.
