State police fire marshals continue to investigate a blaze that destroyed a central Pennsylvania home and left the married couple who lived there in critical condition.
However, three of the couple's four children are now out of the hospital, and the fourth is improving.
George and Heather Radabaugh, of Middletown, are still being treated at the Lehigh Valley Hospital-Cedar Crest's Burn Recovery Center. Their 7-year-old daughter Gabreana has been upgraded from critical to stable condition.
The couple's 14-year-old son, Griffin, was listed in critical condition but improved enough to be released from the hospital Sunday.
Their other two children, 18-year-old George Jr. and 12-year-old Gabe, were treated for lesser injuries and released earlier Sunday.
The home caught fire about 1 a.m. Saturday.
Fire marshals aren't expected to announce the results of their investigation until Monday.
