Maricopa County prosecutors have nearly doubled the number of people charged under Arizona’s anti-swarming law since early June, while County Attorney Rachel Mitchell warns violent offenses involving teenagers are increasing across the Phoenix area.
Arizona’s Family reported 124 people had been charged under Preston’s Law through Aug. 12, up from 63 on June 4. The total includes 79 juveniles and 45 adults. “It’s very concerning,” Mitchell said, distinguishing the trend from overall teen crime, which she said fell after the COVID-19 pandemic even as violent cases increased.
Gov. Katie Hobbs signed Preston’s Law in May 2025, and it took effect Sept. 26. The measure classifies an assault committed against one person with the aid of two or more accomplices as aggravated assault. Known as “swarming,” the offense is a Class 4 felony and remains eligible for probation.
The law honors 16-year-old Preston Lord, who died after a group attack outside a Queen Creek Halloween party in October 2023. Mitchell said prosecutors hope the tougher charge deters participants before group violence escalates into another killing.
Youth safety advocate Katey McPherson called the recent numbers “startling” but said criminal penalties are only one part of the response. She urged stronger parenting, community involvement and cooperation between families and local governments.
The county attorney’s office has launched a Teen Advisory Council so high school students can discuss violence, reckless driving and substance abuse directly with prosecutors. Its Report, Don’t Repost initiative urges witnesses to send fight videos to police instead of circulating them online, where missing names and context can hamper investigations.
The rising charge total shows prosecutors are using Preston’s Law frequently during its first year. It does not yet show how many cases have resulted in convictions or whether the statute has reduced teen violence.
