A man accused of shooting a person during a parking dispute in Railroad Springs killed himself last week.

William Frost, 69, was found dead Nov. 9 from a self-inflicted gunshot wound in the backyard of his home on West Zephyr Avenue.

He was arrested for aggravated assault with a deadly weapon on Oct. 5 after allegedly shooting William Cummings, 21, in the cheek on Oct. 3 during a road-rage incident.

Frost pleaded not-guilty to the charge in Flagstaff Justice Court and had bonded out of jail at the time of his death.

Frost almost hit Cummings' car while it was idled on Northwestern Street. Cummings’ injuries were described by police as “non-life-threatening.”

According to Flagstaff Police Public Information Officer Sgt. Cory Runge, Frost was turning left onto Northwestern Street from Route 66 when he nearly hit Cummings, a resident of a nearby townhouse complex.

A friend of Frost told police that Frost had been upset about his recent arrest and was suffering from an unnamed medical condition, according to the police report.

Police did not find a suicide note in Frost's home but his friend said he received an email from Frost on Nov. 9 stating that he would rather die than speak to a family member.

Police could find no personal statements from Frost mentioning his recent arrest.

Frost had grown increasingly agitated with people parking on the street near his home and was described by Runge as a “vocal complainer” about the parking situation in the Railroad Springs neighborhood.
