A 47-year old woman is in custody after allegedly opening fire on a police officer in Bullhead City, AZ early Thursday.
The incident occurred after officers responded to a domestic disturbance between suspect April Dezerienne Silvis and her mother.
As police arrived, Silvis allegedly fired upon the officer with a rifle.
Silvis then barricaded herself inside the house.
After a several hours standoff, SWAT officers used tear gas to force Silvis out of the home. She was taken into custody and transported to a local hospital for a medical evaluation.
