Two young men who were found naked and shot to death near railroad tracks in the Princeton Park neighborhood on the South Side Monday morning had been kidnapped and possibly thrown into the trunk of a car Sunday night, police said.

Dante Coleman, 17, of East 55th Street [Garfield Boulevard] and South State streets and Ibitoye Olayinka, also 17, who lived near the intersection of West 69th Street and South Western Avenue were kidnapped about 11:15 p.m. from near East 51st Street and South Prairie Avenue, police said.

They were found shot to death and naked and lying face down about 8:50 a.m. near the tracks in the 9000 block of South Holland Road.

The men were found suffering from multiple gunshot wounds to their head and back, police News Affairs Officer Veejay Zala said.

The two — who had head trauma — were pronounced dead at the scene at 9:50 a.m., according to a spokeswoman for the Cook County Medical Examiner’s office. Autopsies that will determine the exact cause and manner of death are scheduled for later Tuesday.
