Authorities say a Prescott woman has been accused of attempted homicide following a work dispute.
Prescott police say 24-year-old Ebonice Johnson also is being held in the Yavapai County Jail on suspicion of misconduct involving weapons.
Officers responded to the Walmart store about 6:30 a.m. Saturday after the manager called 911 to report a disorderly woman in the parking lot with a rifle.
Police located Johnson near the back of the store and were able to take her into custody.
They say a rifle was located near her.
Police say Johnson was an employee at the store and had been involved in a verbal altercation with several co-workers during their shift earlier that morning.
Johnson reportedly went home to retrieve the rifle and wrote a note about harming her co-workers.
