A Martins Ferry man is facing additional charges in connection with a child sex crimes case.

WTOV9.COM reports 23-year old Ryker Hill was recently indicted by a Belmont County grand jury on nine felony sex-related charges against minors. 

The investigation began while Hill was applying for a position with the Ohio State Highway Patrol a couple of months ago. At that time, Hill was set to take a polygraph test at the OSHP academy in Columbus. Before the test, Hill was questioned and allegedly admitted to looking at child pornography more than 400 times. 

Hill also allegedly admitted to “groping incidents” with three juveniles over the last four to five years.
