Marion Thompson wore a shirt and two buttons honoring the memory of her 31-year-old son Carlton Holland.
She called NewsChannel 3 begging and pleading for answers.
"My son is not going to die in vain. He needs to be at peace," says Thompson.
Nearly five months after her son was shot and killed, no one knows who did it.
"Everybody talks about how good he was and how he would have your back and everything, but nobody's got his back right now,” says Thompson.
Suffolk police say Holland, or CJ as friends called him, was at a New Year's Eve party in the 400 block of Linden Avenue.
Witnesses say CJ and another man got into an argument.
Around 3 a.m., police say, gunshots were heard. They say CJ later died at the hospital with a gunshot wound to the chest.
"They took something from me that can never be replaced. They took something from me. They left a hole in my heart," says Thompson.
She says someone, somewhere knows something.
"If you know about this, if you know who did this to him and you're not telling then you might as well had the gun in your hand," says Thompson.
