Two students at Southern Illinois University in Edwardsville have died a day after a fire in their off-campus apartment unit.

A spokeswoman for St. Luke's Hospital in suburban St. Louis says 21-year-old Lacy Siddall and 19-year-old Lauren Petersen died there Monday.

Firefighters responding to the blaze early Sunday found the two women in a room next to a bedroom that was on fire in their second-floor apartment.

Authorities say the two victims were childhood friends who grew up in Bethalto.
