Multiple live rounds found among dummy bullets on 'Rust' set

When evidence was collected on the “Rust” set, live rounds were found mixed with dummy bullets on a prop cart, inside a munition box and in gun holsters for two actors, crime scene technician Marissa Poppell testified.

Led by Baldwin's defense team, Poppell identified the live bullets in photos presented in court. The live rounds appear to have a silver dot at the bottom of the casing rather than a dull gold or bronze shade.

"Your working theory, as you evaluated the ammunition and looked at the similarity between the Starline nickel live and the Starline nickel dummies is that they could have been easily commingled there?" Spiro asked.

"Yes," Poppell responded.

"In other words, somebody could have mistaken one for the other, right?" He continued.

"Yes," she said.

Damaged firearm focus on cross-examination

Baldwin's attorney, Alex Spiro, kicks off today with a cross-examination of the crime scene technician for the Santa Fe County Sheriff’s Office called by prosecution yesterday.

Spiro questioned Marissa Poppell on the damage caused by the state's forensic analysis of the gun. Baldwin's defense team tried to have the case dismissed because they were unable to examine the gun but were denied by Judge Sommer.

"As to the firearm, I think where you left off yesterday is ultimately that firearm was destroyed in the testing there," Spiro said.

"Not destroyed, but broken," Poppell responded.

Poppell later agreed that although the gun could likely be fixed with replacement parts, it could not be restored to the condition it was on the day that Halyna Hutchins and Joel Souza were shot.

Second day of trial begins

Baldwin is in court for the second day of trial with his family once again seated in the gallery behind him.

His wife, Hilaria, has returned to court along with his brother Stephen and sister Elizabeth Keuchler. Stephen Baldwin is wearing a headset typically used for the hearing impaired.

In yesterday's opening statements, the prosecution painted the "Rust" star as recklessly breaking the cardinal rules of gun safety. His defense pushed back, telling the jury that Baldwin was told by those responsible for safety that the gun was "cold" — or without live ammunition.
