Woman arrested after threatening coworkers, store with a rifle, a knife, and a torch

A bungled case of attempted workplace violence, here. Excerpt:

'A Prescott woman is facing attempted homicide and arson charges after she returned to work following a dispute armed with a knife, a rifle and a torch.

Around 6:28 a.m. on Saturday, Dec. 3, Prescott police responded to the Wal-Mart store at 3050 Highway 69 in Prescott, after the manager of the store called 9-1-1 to report a disorderly woman in the parking lot with a rifle.

Officers found 24-year-old Ebonice Johnson, Prescott, near the back of the store and took her into custody without incident.
...
Detectives served a search warrant at Johnson's home and located evidence related to her intentions and plans to harm her co-workers. At this point it appears Johnson was motivated by her dissatisfaction at work and the investigation is not revealing any other cause for her extreme behavior. Johnson was booked into the Yavapai County Jail on charges including four counts of attempted homicide (pre-meditated), arson of an occupied structure, and weapons misconduct-all are felony charges.

Johnson lawfully purchased the rifle a year and a half ago and had no previous convictions related to weapons misconduct.'
