Area residents reported hearing several shots fired at shortly before 1:30 a.m. in the 5300 block of Lindsey Avenue near Catherine Street.
Authorities said responding deputies arrived at the home to find the woman with a gunshot wound to the head. The woman was transported to a local hospital.
In a statement at 4:40 a.m., the sheriff's department reported the woman had died. At about 6 a.m., authorities retracted their initial statement and said the woman was listed in critical condition.
The woman's mother was inside the home at the time of the shooting and even heard the gunshots, but she did not know that her daughter had been shot until authorities arrived.
Though the victim was shot while she was inside the home, deputies said the shooter fired from outside the home.
Deputies did not have a suspect description as of Thursday morning.
