A New Mexico judge, Mary Marlowe Sommer, has upheld the dismissal of involuntary manslaughter charges against Alec Baldwin related to the fatal shooting of cinematographer Halyna Hutchins on the set of 'Rust'. The dismissal stemmed from allegations that police and prosecutors withheld crucial evidence, including ammunition possibly connected to the shooting. Prosecutor Kari Morrissey challenged the dismissal, but the judge rejected the motion as repetitive and untimely, citing procedural errors and excessiveness. Morrissey intends to appeal, although Baldwin maintains he did not pull the trigger of the revolver that killed Hutchins and injured director Joel Souza during a rehearsal. The decision impacts Baldwin's legal position and highlights issues of evidence handling in high-profile cases.
