In a phone conversation before he was arrested, Marks told Channel 6's Jasmin Caldwell, Scott's disappearance was sad but that he had nothing to do with it.
"Not only do I have no history of violence towards women or children, I teach free women's assault programs or did before I went on the run away from her," said Marks.
Meanwhile, the mother of two of Marks' other children, Ginelle McDonough, and another woman, Maya Maxwell, were being held in the Muskegon County jail in Michigan for Temple Police.
Muskegon Police said their fugitive team arrested the women Jan. 11.
Maxwell is charged with Obstructing Police/Evidence Destroying. McDonough is charged with Harboring a Fugitive, according to Muskegon Police.
McDonough is identified as Marks' wife in the court documents from Washington state. She said they were married in October, 2003.
