Rocks rained down on passing vehicles along Arizona's State Route 74 Tuesday, damaging at least five cars and affecting or endangering at least seven victims before the suspect bolted on foot and was chased down by state troopers. The attack unfolded somewhere along the stretch of highway also known as Carefree Highway, though authorities have not said exactly where the rocks were thrown.
Chaos on a Rural Stretch of Highway
According to AZ Family, investigators say the man threw rocks at passing drivers on the Arizona freeway, and the Department of Public Safety reported that the barrage had hit at least five cars. Investigators reported at least seven victims were affected by the incident. When troopers arrived on scene, the man ran, and troopers chased after him before eventually taking him into custody.
State Route 74 runs east to west between U.S. 60 south of Wickenburg and Interstate 17 in north Phoenix, a largely rural corridor that locals know as Carefree Highway, per the same report. DPS did not say exactly where along that stretch the rocks were thrown, leaving the precise location of the attack unclear.
Conflicting Accounts of the Suspect's Identity
AZ Family reported that the man's name had not been released. However, FOX 10 identified the suspect as 64-year-old Adam Clayton, reporting that troopers arrested him after he allegedly hurled rocks at moving traffic on State Route 74 and tried to flee into the open desert. The two outlets' accounts diverge on whether the man's identity was public, and both versions are presented here as reported.
FOX 10's account of the damage largely mirrors AZ Family's, reporting that the suspect had struck and damaged at least five vehicles, impacting seven victims. The station also reported that the man was booked into jail, listing six felony charges of aggravated assault with a deadly weapon or dangerous instrument plus five counts of felony criminal damage, with bond set at $25,000. AZ Family similarly reported that the man was booked on multiple charges of criminal damage and aggravated assault, though it did not specify the exact count breakdown reported by FOX 10.
Court Date and Possible Charges
FOX 10 reported that the suspect identified as Clayton is scheduled to make his next court appearance on Oct. 27. Arizona law addresses the alleged conduct under two statutes: criminal damage is defined under Arizona Revised Statutes § 13-1602, while aggravated assault falls under Arizona Revised Statutes § 13-1204.
DPS used the incident to issue a broader public safety message, saying throwing objects at moving vehicles isn't a prank and that it can cause serious crashes, injuries, or fatalities. The agency urged anyone who witnesses dangerous behavior on Arizona roadways to safely report it to law enforcement, adding that doing so helps keep the roads safe for everyone.
A Highway With a Tragic History
The warning carries weight in Arizona, where rock-throwing on highways has turned deadly before. FOX 10 noted that in July 2018, rookie DPS Trooper Tyler Edenhofer was killed after responding to reports of a pedestrian hurling rocks at vehicles along Interstate 10 near Avondale. That history underscores why troopers treated Tuesday's chase as a serious public-safety threat rather than a minor nuisance call.
