MASON CITY, IOWA - The personal journal of a missing TV anchorwoman was mailed to the local newspaper from an unknown source, and authorities are looking into it.

Jodi Huisentruit, 27, a KIMT-TV morning news anchor and a native of Long Prairie, Minn., disappeared on her way to work on June 27, 1995.

Law enforcement officials have followed thousands of leads in a case publicized nationally. Many details of the case, including the 84-page journal, remain confidential.

The Mason City Globe Gazette received the journal in a large envelope with no return address. The June 4 postmark was from Waterloo. Representatives of both agencies confirmed that the copy was a reproduction of a journal they took into evidence after searching Huisentruit's apartment.

Jeff Jacobson, special agent in charge with the Iowa Division of Criminal Investigation, said an internal probe will try to determine who leaked the journal, though its release is not likely to compromise the 13-year investigation. He believes it came from an investigating agency such as the division or Mason City police but doesn't know why.

"You tell me," he said. "There's several different things I could think of off the top of my head. It could be trying to make people look bad, a secretary, who knows? It could be anybody that would have access to that."
