TLDR
Police in Glendale, Arizona, say Arianna Foster and Alexander Black used the same damaged Kia in three alleged road rage incidents near a Walmart and on Loop 101, leaving multiple drivers and a child at risk and facing felony assault charges.
The Walmart parking lot in Glendale, Arizona, became a recurring backdrop for what officers describe as a month of escalating roadside confrontation. By mid-March, investigators say the same 2009 Kia Spectra was tied to three separate encounters, with rocks, bricks, pepper spray, and a hatchet all allegedly brought into play.
Prosecutors in Maricopa County have charged 20-year-old Arianna Foster and 24-year-old Alexander Black with aggravated assault, criminal damage, and endangerment, according to a probable cause statement reported by Law & Crime. Both remain in the Maricopa County Jail on a $150,000 bond while the case moves forward.
Jail booking photos released by the Maricopa County Sheriff’s Office show Black and Foster, who are accused of using their Kia, described in the affidavit as missing both bumpers, in each of the alleged confrontations.
Pattern of Alleged Parking Lot Attacks
According to the probable cause statement, the first incident took place on February 19th at a Walmart in Glendale. A man driving with his 8-year-old daughter told police a Kia trailed them so closely he could no longer see its headlights, then followed them into the lot, where Foster allegedly spat in his face and threw a river rock at his vehicle from a few feet away.
As the man tried to get away, officers wrote, Black chased him while holding a hammer, then later threw another rock that struck the hood and narrowly missed the windshield. Police estimated about $2,000 in damage and said the act put both the driver and his child in danger. Four days later, in the same parking lot, the same Kia allegedly honked, followed another driver, and pulled alongside, where Foster is accused of throwing two bricks, the second of which struck the car and caused about $2,500 in damage. Surveillance video, investigators said, captured the vehicle and its license plate, linking the two parking lot cases.
Highway Confrontation on Loop 101
The third alleged incident occurred on March 18th on southbound Loop 101 near Olive Avenue. A driver trying to pass the Kia told officers that Black sped up, cut him off, and abruptly braked, leading to a rear-end collision before Black eventually pulled over on the shoulder.
When the man approached and asked, “What the hell was that?” Foster allegedly responded by spraying him in the face with pepper spray. According to the complaint, Black then used a hatchet to chop off a side mirror and strike the passenger door, and a knife to puncture the front and passenger-side tires. The victim later told police he was “scared” and felt he was in mortal danger during the encounter.
Charges, Evidence, and Public Safety Concerns
The probable cause statement describes a series of incidents concentrated within roughly one month, involving the same vehicle, similar tailgating behavior, and escalating alleged use of improvised weapons, from rocks and bricks to pepper spray, a hatchet, and a knife. Officers documented thousands of dollars in property damage and noted that one of the encounters involved a young child seated in the targeted car.
Under Arizona law, aggravated assault can apply when a person uses a dangerous instrument or causes, or attempts to cause, serious physical injury, while endangerment covers conduct that places someone at substantial risk of imminent death or injury. Prosecutors cite those statutes in the charges against Foster and Black, who are presumed innocent unless and until proven guilty. Their current detention on a $150,000 bond reflects the court’s assessment of the alleged pattern of behavior and the potential risk to the public while the case proceeds.
The allegations against Foster and Black turn routine acts of driving and parking into a criminal court file that now spans multiple victims, locations, and weapons. In the coming proceedings, prosecutors will be required to substantiate the pattern described in police reports, and defense attorneys will have the opportunity to challenge how each roadside encounter unfolded.
