The woman charged in connection with the disappearance of a missing child pleaded not guilty Tuesday.

Jennifer Snyder entered her plea during a video arraignment to charges of tampering with evidence, endangering children, permitting child abuse, and gross abuse of a corpse. 

In an new investigation opened by Youngstown Police in May, detectives said they believe 16-year-old Jimmy Higham died in June 2001 while in the legal custody of Snyder.
