Does anyone know when this woman disappeared?

So both NamUs and the Ohio Attorney General’s Office give Chelsey Coe’s disappearance as July 1, 2017. I found this article her mom reported her missing in July after last hearing from her in June, but then this article saying she was last seen in August and her mom last heard from her in “June or July.”

If Chelsey disappeared in June, I can post her now, and I’ll be able to post her either now or soon if she disappeared in July. But if she went missing in August this case will have to wait at least another month.

Since she was last known to be living with some man whom I gather is a suspect in her case (they did search his yard with ground-penetrating radar after all), perhaps no one knows precisely when she went missing.

Help?
