Rainelle, W.Va. (AP) -- One week after a series of explosions rocked a western Greenbrier County home, one person remains in critical condition, while two others are serious.
A spokeswoman for Charleston Area Medical Center said Tacy Patterson remained in critical condition Monday.
Kelly Wickline and Tiffeny Williams were in serious condition at the University of Virginia Health System in Charlottesville, Va.
Patterson's daughter Tara was upgraded to fair.
Her son Terry Patterson Jr. and husband Terry Patterson Sr. have been released.
Authorities still don't know what sparked three explosions followed by a fire at the Pattersons' home near Rainelle on Nov. 23.
Greenbrier County chief deputy Kirby Hanson said a state fire marshal and deputy returned to the scene Monday.
