"So Mr. Halls took custody of the weapon and at that point she was doing her other duties as key prop assistant," he added.
In a statement released after the TV interview, Reed's attorneys said she was "incredibly safety conscious" on set.
The statement added: "Never in a million years did Hannah think that live rounds could have been in the 'dummy' round box. Who put those in there and why is the central question."
In the wake of the shooting, Baldwin called for a police presence on the set of every film or TV show that features guns.
"Every film/TV set that uses guns, fake or otherwise, should have a police officer on set, hired by the production, to specifically monitor weapons safety," he tweeted Nov. 8.
A day after the shooting, Baldwin tweeted: "There are no words to convey my shock and sadness regarding the tragic accident that took the life of Halyna Hutchins, a wife, mother and deeply admired colleague of ours."
The actor has since made his Twitter account private.
