FAIRMONT CITY, Ill. (AP) — Fire swept through a trailer home, killing a woman, her two children and her uncle who were unable to flee because the back door had been improperly covered over by vinyl siding, the police chief said.

The woman's husband managed to escape the Tuesday night inferno in this St. Louis suburb by breaking and crawling through a window in a rear bedroom, only to find his efforts to re-enter the home thwarted by intense flames and smoke, police Chief Scott Penny said.

The family had moved into the home in the HavaHome Mobile Home Park on Saturday without getting a required inspection of its fitness for occupancy, Penny said.
