Ohio 'House of Horrors' Mom Raises Eyebrows with Mysterious Arm Mark

The mother of 16 kids kept crammed in a sickening house of horrors cowered as she was booked into jail — and appeared to try and hide a mysterious mark on her arm, new footage shows.

Elizabeth Siders, 33, looked frightened and submissive as she was searched by officers at the Southeastern Ohio Regional Jail on July 1 after she, her husband and her in-laws were found living in squalor with the children at their home, according to video from the facility obtained by Plunder True  Crime.

Wearing a baggy red T-shirt, sweatpants and orange flip-flops, Siders kept her head down and obediently complied with the officers’ commands — and continued to rub and cover a dark mark on her left arm, the footage, which has no audio, shows.
