(CNN)Prosecutors say the police officer who killed 12-year-old Tamir Rice outside a Cleveland recreation center last year won't face criminal charges. Neither will the other officer who was with him.

An Ohio grand jury decided not to indict Officers Timothy Loehmann and Frank Garmback, prosecutor Tim McGinty said Monday.

"Given this perfect storm of human error, mistakes and communications by all involved that day, the evidence did not indicate criminal conduct by police," McGinty said.

Loehmann, an officer-in-training, shot 12-year-old Tamir on November 22, 2014. Garmback was training him.

"It is likely that Tamir, whose size made him look much older and who had been warned his pellet gun might get him into trouble that day, either intended to hand it over to the officers or show them it wasn't a real gun," McGinty said. "But there was no way for the officers to know that, because they saw the events rapidly unfolding in front of them from a very different perspective."

It was "reasonable" to believe the officer who killed the boy believed Tamir was a threat, the prosecutor said, adding that the toy gun looked real.

A recent FBI video analysis, the prosecutor said, showed Tamir "was drawing his gun from his waist as the police slid toward him and Officer Loehmann exited the car." After the shooting, officers discovered it was a toy gun.

The shooting swiftly sparked controversy given Tamir's age and the fact that he had a pellet gun, not a handgun.

In a statement released Monday evening, Tamir's family accused the prosecutor's office of mishandling the case.

"Prosecutor McGinty deliberately sabotaged the case, never advocating for my son, and acting instead like the police officers' defense attorney," the statement said. "In a time in which a nonindictment for two police officers who have killed an unarmed black child is business as usual, we mourn for Tamir, and for all of the black people who have been killed by the police without justice. In our view, this process demonstrates that race is still an extremely troubling and serious problem in our country and the criminal-justice system."

In an earlier statement, the family said it was grateful for community support, calling for those upset with how the case was handled to respond "peacefully and democratically."

"We renew our request that the Department of Justice step in to conduct a real investigation into this tragic shooting of a 12-year-old child," the family said.

The prosecutor hasn't responded to the family's accusations. On Monday, he repeatedly told reporters that no crime was committed by police and said he'd recommended the officers shouldn't be indicted.
