A Kentucky woman who is suspected of killing her husband and two teenage daughters was shot by police after pointing her gun at an officer.

Courtney Taylor, 41, was taken to a nearby hospital with life-threatening injuries after she was shot by a deputy at her Williamsburg home on Friday night.

Authorities said her husband Larry Taylor, 51, and their daughters Jessie, 18, and 13-year-old Jolee were found dead inside the house.

Police were called to the home around 10.12pm when a relative went to the residence to check on the family, police said.

'He must've observed a body and retreated,' Sheriff Colan Harrell told the Lexington Herald-Leader.

Two deputies arrived on the scene and entered the home when they said Taylor pointed her pistol at them.

That's when one of the deputies shot her. Taylor's current condition is unknown.

Harrell said he personally knew the Taylors and found the incident to be 'unbelievable'.

He said his department has never received any calls reporting trouble at their home in the past.

Harrell said he believes Larry Taylor and his daughter had been dead for several hours before their bodies were found.

Investigators said they were shot in their beds, according to WKYT.

Harrell said all signs point to Taylor, a registered nurse, being the one who killed her husband two children.

The motive remains unknown.

Both deputies involved in Courtney Taylor's shooting have been placed on administrative leave, as is standard protocol.

Authorities plan to charge Taylor and Kentucky State Police is taking over the investigation.

Family members immediately began to change their profile pictures to Larry, Jessie and Jolee as tribute to the family on Saturday.

'He was a big teddy bear,' Elizabeth Kidd commented on Facebook.

'Such a loving father and husband. I just don't understand.'
