The second boy accused of shooting another teenager in January 2015 at the Corrine Reid Owens Transit Center will find out June 20 how much time he’ll spend in prison.

Naceir Mayes, 16, entered a guilty plea April 1 to the most serious charge against him – first degree attempted intentional homicide – which was amended to first degree reckless injury with use of a dangerous weapon, party to a crime. He also entered a plea to possession of a firearm by a felon. The charge of marijuana possession with the intent to deliver was dismissed but was read into the record.

Court records say Racine County Circuit Court Judge John Jude issued a “finding of guilt based” on the plea and ordered pre-sentencing. Mayes will be sentenced June 20.

Mayes and Lamont Koker, 18, were charged last year with a mix of charges, the most serious of which was first degree attempted intentional homicide, after police say they confronted a rival gang member at the transit center on State Street. The boy was shot twice; one bullet struck him in the chest, and the other bullet passed through the sleeve of his sweatshirt but did not hit him.

Koker agreed last December to plead no contest to the charges against him, and he was sentenced in February to 10 years in prison followed by 10 years of extended supervision.

Mayes has additional charges pending against him for allegedly participating April 20 in the beating of another inmate in the Racine County Jail. If convicted of these new charges – battery by prisoner and disorderly conduct – Mayes could get an extra six years in prison and/or face up to an additional $11,000 in fines on top of whatever sentence Jude assigns him next month for the transit center shooting.
