The Collin County Sheriff's Department is investigating an officer-involved shooting late Thursday afternoon.
Collin County deputies were serving a warrant along County Road 580 just east of State Highway 78 in the town of Blue Ridge, according to sheriff's spokesman John Norton.
The man at the home allegedly opened fire on the deputies and then reportedly ran inside and shot his mother and himself.
The sheriff's office reported the man was killed, but later said he was not dead and was being worked on by paramedics.
The man and his mother were taken by helicopter to a hospital.
Their conditions were not immediately known.
No officers were injured, according to Norton.
