Officials say a house fire that injured an elderly Wausau woman Monday was set on purpose.
Investigators say the fire on Elm Street may have been started by the 81-year-old woman who lives there. A neighbor says she may be depressed about the death of a close friend.
Officials are still trying to determine what, if any, charges they will file.
As of Tuesday, the victim remained in serious condition at the Wausau Hospital
