SPARTA, Ill. (AP) — A coroner says two brothers who were paralyzed after separate car wrecks died when fire consumed their southern Illinois home.

Randolph County Coroner Randy Dudenbostel says 45-year-old Dennis Monroe and 42-year-old Willie Monroe were killed in the fire near Sparta on Tuesday.

A third brother, his wife and young son managed to flee the two-story house but suffered burns and smoke inhalation. They were taken to a hospital, but there's no word on their conditions Thursday.

The cause of the fire hasn't been determined, although officials suspect it was caused by a wood-burning device.

The Illinois State Fire Marshal's Office is investigating.
