ST. LOUIS - Homicide detectives were called out to an apartment in south city, where police found two men dead inside Wednesday.

Police believe both men died inside the apartment after being shot near Hydraulic Avenue and Meramec Street. Police received a call around 9 a.m. from a man looking for a friend.
