Two more people accused of aggravated assaults in a rash of teen violence cases in Gilbert and the East Valley were indicted, Maricopa County Attorney Rachel Mitchell announced on Thursday.

Also, a third teen already indicted for aggravated assault was indicted again, this time on several drug charges from an incident unrelated to the aggravated assault, according to Mitchell's office.

Cody Michael Kostoryz and Gage Silas Garrison were indicted on Feb. 15 for their alleged role in assaulting a person at a party on Dec. 17, 2022. Also on Feb. 15, Kyler Matthew Renner was indicted on six drug-related charges for an incident on March 29, 2023. Garrison and Renner were already indicted for aggravated assault for their alleged role in a Dec. 3, 2022 assault.

In early February, Mitchell's office announced the indictments of Garrison, Renner, Jack Jay Woods, Tyler Allen Freeman and William Owen Hines for their alleged roles in teen violence cases in the East Valley.

Her office has publicly announced the indictments of nine people across seven cases since January for assault in Gilbert and the East Valley. On Thursday, Mitchell's office said prosecutors have 27 open cases from submittals received from two East Valley police departments and have charged 19 individuals — adults and juveniles — with 52 total counts.

Mitchell’s announcement this week comes as intense media scrutiny over the Gilbert Goons continues in the wake of Preston Lord’s beating death in October. None of the indictments are related to Lord’s death, according to Mitchell's office.

Mitchell's office has announced several indictments since January:

In the Dec. 3, 2022 incident, Garrison, Renner and Woods allegedly used brass knuckles to attack a man at a parking garage in downtown Gilbert, according to court documents. The victim suffered head, jaw and torso injuries, according to court documents.

Arizona lawmakers are now considering banning brass knuckles.

On Jan. 25, a $75,000 bond was set for Garrison, who also faces electronic monitoring and a curfew if released from jail, according to court documents. A $100,000 bond was set for Renner, who also faces electronic monitoring and a curfew if released from jail.

The victim told police he went to downtown Gilbert after spending time with friends at the In-N-Out Burger at 2449 S. Market St., in Gilbert. The fast-food restaurant is at the center of complaints about incidents of teen violence by the Gilbert Goons.

A group of men wearing black caps — allegedly Garrison, Renner and Woods — approached the victim in the parking garage and attacked him, according to probable cause statements from Gilbert police.

“The victim reported he was thrown to the ground and saw a subject with brass knuckles but could not recall if they were used,” according to the statements.

Gilbert police said a video of the incident showed Garrison punching and kicking the victim in the face. When officers arrested Garrison on Jan. 24, he allegedly told them he was familiar with the attack and identified himself in a video of the incident.

Garrison told police he attacked the victim after “perceiving the subject was threatening them,” according to a probable cause statement.

“It should be noted the video and other witness statements differ from Gage Garrison’s account,” police said.

On Jan. 31, Gilbert police announced three arrests and said it’s made 35 arrests involving teen violence — including 22 arrests in January.

Gilbert police arrested Renner on Jan. 24 for his alleged role in two incidents — a November 2022 assault near a residence at Higley and Riggs Roads and the December incident at the parking garage. While searching the Renner home, police allegedly found drugs and arrested Travis Renner, 50, and Kiara Holsapple, 20, on drug charges. Travis Renner is Kyler's father.
