YOUNGSTOWN — Judge John Durkin of Mahoning County Common Pleas Court ordered that brother and sister Marquez D. Thomas, 24, and C’Mone Thomas, 22, be held in the Mahoning County jail without eligibility to make bond.

Both are charged with aggravated murder, murder and multiple counts of felonious assault in the Dec. 30, 2021, shooting death of Joseph Addison, 42, at an apartment complex on Tyrell Avenue on the West Side. Police said two men, 34 and 21, and a woman, 26, also were wounded at the complex that morning.

During a hearing Thursday, Detective Jerry Fulmer of the Youngstown Police Department testified about evidence he gathered.

Afterward, Durkin announced he would deny bail for the siblings because Fulmer testified a video shows C’Mone Thomas carrying an AR-15 rifle into one of the apartment buildings at the complex that day.

He said the evidence also suggests there is a video showing Marquez Thomas carrying that or another AR-15 rifle “out of that family dwelling, that there was a shooting,” and that Addison died.

The judge said there is “some question, I suppose” as to whether prosecutors proved beyond a reasonable doubt whether the other victims “were shot as it relates to this incident or a prior shooting earlier that day.”

He said there is no question that an AR-15 rifle is capable of traveling through a victim, as well as doors and walls when fired into a dwelling such as the apartment complex, “including people of all ages.”

He said the evidence presented established that the “presumption is great” that the accused committed the offense for which they are charged.

He said he is including C’Mone Thomas in that analysis, noting that a person can be charged as the principal offender or an aider or abetter.

Durkin said the evidence presented shows that both “pose a substantial risk of serious physical harm to a person or community.”

The judge also noted that C’Mone Thomas did not turn herself in on her charges for four months and “was seen on Instagram with a firearm and Monopoly money and a sign that said ‘fugitive.'”
