NASHVILLE, Tenn. (AP) — A Tennessee judge on Wednesday seemed ready to agree with an attorney for Nashville police that the writings of a school shooter could be released as public record once the investigation is officially closed.

But the parents of children at the Covenant School added an extra twist to an already complicated case by asserting that they have gained legal ownership of the writings from the shooter’s parents and now hold the copyright.

None of the eight attorneys arguing before Davidson County Chancery Court Judge I’Ashea Myles during a two-day hearing claimed to be a copyright expert. Their answers to Myles’ pointed questions about the interplay of federal copyright protections and the Tennessee Public Records Act seemed at times only to muddy the waters further.

In the end, Myles said she will write an order outlining specific questions she wants them to address. Only after that will she rule on when, if ever, the writings can be released to the public.
