SANTA FE, N.M. (AP) A New Mexico judge has upheld her decision to dismiss an involuntary manslaughter charge against Alec Baldwin in the fatal shooting of a cinematographer on the set of a Western movie.

In a ruling Thursday, state District Court Judge Mary Marlowe Sommer stood by her July decision to dismiss an involuntary manslaughter charge against Baldwin. The case was thrown out halfway through trial on allegations that police and prosecutors withheld evidence from the defense in the 2021 death of cinematographer Halyna Hutchins on the set of the film Rust.

Baldwins trial was upended by revelations that ammunition was brought into the Santa Fe County sheriffs office in March by a man who said it could be related to Hutchins killing. Prosecutors said they deemed the ammo unrelated and unimportant, while Baldwins lawyers say investigators buried the evidence in a separate case file and filed a successful motion to dismiss.
