Those new charges we’d been waiting on against Ingmar Guandique, the man accused of murdering Chandra Levy, were filed today in D.C. Superior Court, the Associated Press (via WTOP) is reporting. Initial speculation was that the new charges, which have pushed back Guandique’s trial until much later in 2010, might have had something to do with another victim. Instead, it turns out he’s being charged with threatening a witness.

According to the new indictment, Guandique wrote a note to a witness identified only as “J.G.” and had someone deliver it. The note threatened to kill J.G. or J.G.’s family if J.G. cooperated with law enforcement in the case against Guandique.

A second threatening letter was mailed to the witness by someone involved in the alleged conspiracy, according to the charges.

No word on who that other person who allegedly helped Guandique mail the letter might have been.
