Pater continued the hearing until Oct. 16, but ruled that because Tunstall has not waived his right to a speedy trial, which is required in 90 days if incarcerated, the days he has requested to hire an attorney would not count in that time frame for trial.
Prosecutors say Tunstall conspired with Miquan Hubbard, 18, also of Hamilton to gun down Gilbert, an eighth-grader at Wilson Middle School.
Hamilton police arrested Hubbard three days after the slaying of Gilbert. According to court documents, Hubbard is accused of being the shooter.
Gilbert was shot and killed at about 6:30 p.m. Aug. 29 at an apartment complex in the 800 block of Front Street, police said.

Hubbard’s case is pending in Judge Michael Oster’s courtroom where a bond dispute is ongoing.
