Lead detective in Alec Baldwin case to testify, convicted armorer may be called in 'Rust' trial

The lead detective in the shooting of cinematographer Halyna Hutchins on the set of the film ''Rust'' is likely to be on the stand for most of Friday at Alec Baldwin 's involuntary manslaughter trial in New Mexico, as prosecutors try to cast the movie star as a reckless cavalier with a gun in his hand and the defense seeks to portray him as a working actor just doing his job.
