When NPR pointed out the agency's own records show that Otto failed to pay, Ketchum says his agency tried. We attempted through debt collection to get penalties from that individual. I'm not going to comment on Mr. Otto. The incident involving Maddox and Higgins marked the third time that OSHA cited Otto for violating trenching regulations.
