Baldwin's case will be brought before a grand jury in mid-November, special prosecutor Kari Morrissey said on Tuesday.
The move followed results of an independent forensic test that found Baldwin had to have pulled the trigger of a revolver he was rehearsing with for it to fire the live round that killed Hutchins and wounded director Joel Souza.
The finding was the same as a previous FBI test on the firearm.
“After extensive investigation over the past several months, additional facts have come to light that we believe show Mr Baldwin has criminal culpability in the death of Halyna Hutchins and the shooting of Joel Souza,” Morrissey and Jason Lewis said in a statement.
Baldwin has said he is not responsible for Hutchins' death and he did not pull the trigger.
"It is unfortunate that a terrible tragedy has been turned into this misguided prosecution. We will answer any charges in court," Luke Nikas and Alex Spiro, lawyers for Baldwin, said in a statement.
The 30 Rock actor was originally charged with involuntary manslaughter in January this year for Hutchins' death, along with the movie's chief weapons handler Hannah Gutierrez, who faces a trial next year.
The planned grand jury marked a setback for Baldwin after prosecutors dismissed charges against the actor in April after new evidence the gun he used might have been modified, allowing it to fire without the trigger being pulled.
Morrissey said if new testing of the gun showed it was working, she would recharge Baldwin.
Prosecutors often use grand juries as they are an easier means to prove probable cause and proceed to trial than filing a criminal complaint that can be probed by defence lawyers at a preliminary hearing, legal experts say.
