Three more child sex crime arrests made in Greenville County

Greenville County Sheriff's Office investigators arrested three men this week on child sex crime charges.

One of the cases was connected to the 45-suspect bust, operation "Millstone," from earlier this month, according to a Friday press release.

The arrest of Donald Mccall, 53, of Simpsonville, is tied to operation "Millstone," according to the Sheriff's Office. He's charged with attempting to disseminate obscene material to a person under the age of 18, first-degree attempted sexual exploitation of a minor, and criminal solicitation of a minor.

Investigators also arrested Kenneth Oshaughnessy, 47, of Simpsonville, and Luis Colon Yera, 26, of Greer. Those arrests stemmed from separate investigations, according to the Sheriff's Office.

Both Oshaughnessy and Yera were charged with second-degree sexual exploitation of a minor.

Oshaughnessy and Mccall have both been released on bond, while Yera is still in custody at the Greenville County Detention Center, according to the Sheriff's Office.
