Kyles was indicted in June on a charge of participating in a criminal gang for allegedly burning an item taken from a memorial of Joseph Davis, 17, who was shot and killed in May 2018 as part of ongoing gang activity, according to police.
Gonnii White, 17, was convicted in June of Davis’ murder with specifications for the use of a firearm and participating in a gang. He was sentenced to life in prison with the possibility of parole after 21 years.
According to Middletown Detective Kristi Hughes, Kyles posted a video himself on social media burning a stuffed animal taken from Davis’ memorial and making gang signs and gang affiliation comments. That led to the indictment.

Kyles, who turned 18 in March, has had 15 contacts with Butler County Juvenile Court since July 2015.
Charges included multiple counts of domestic violence, disorderly conduct, assault, disorderly conduct, inducing panic and multiple probation and parole violations, according to juvenile court records.
