The investigation into the shooting of two people on the set of Alex Baldwin's movie 'Rust' continues. Director of photography Halyna Hutchins was killed and director Joel Souza injured. Reports say first assistant director David Halls picked up one of the three prop guns that had been set up by armorer Hannah Gutierrez and yelled “cold gun.” "Cold gun" is industry slang meaning the gun did not contain live rounds. Halls gave the gun to Baldwin who was using the gun to rehearse a scene. The search warrant said Baldwin was aiming the weapon at the camera when he fired, striking Hutchins and Souza. Reports have surfaced that the weapon was used for target practice by crew members that morning.Joining Nancy Grace today:Paul Szych - Former Police Commander, Author: "StopHimFromKillingThem" on Amazon Kindle, StopHimFromKillingThem.com, Twitter: @WorkplaceThreat, Screen Actors Guild-Eligible Actor, Experience using firearms with blanks during live-action movie scenes (Terminator: Salvation)Domenic Romano - NY Corporate Lawyer and Entertainment Attorney, Romano Law www.romanolaw.comDr. Shari Schwartz - Forensic Psychologist (specializing in Capital Mitigation and Victim Advocacy), www.panthermitigation.com, Twitter: https://twitter.com/TrialDoc, Author: "Criminal Behavior" and "Where Law and Psychology Intersect: Issues in Legal Psychology"Karen L. Smith - Forensic Expert, Lecturer at the University of Florida, Host of Shattered Souls Podcast, @KarensForensic, barebonesforensic.comDr. Michelle Dupre - Forensic Pathologist and former Medical Examiner, Author: “Homicide Investigation Field Guide” & "Investigating Child Abuse Field Guide", Former Police Detective Lexington County Sheriff’s DepartmentAlexis Tereszcuk - CrimeOnline.com Investigative Reporter, Writer/Fact Checker, Lead Stories dot Com, Twitter: @swimmie2009 See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
