Timothy Loehmann, the former Cleveland Police Department officer who shot Rice, was found to have lied on his application to the department, according to Cleveland Director of Public Safety Michael McGrath, leading to his termination, the Cleveland Plain Dealer reported.
"I think our officers have learned that there are best approaches to incidents and with the training that they are receiving, to bolster the training they've had in the past, hopefully we won't have any more incidents like this", he said.
Records made public by another police department where Loehmann worked prior to joining the Cleveland force, showed that supervisors there had wanted to fire him for emotional instability.
"The disciplinary letter cites a letter in Loehmann's personnel file from Independence that says he was emotionally immature and had 'an inability to emotionally function.' The letter also cites an emotional breakdown Loehmann had on the gun range in Independence". He had not yet completed his six-month probationary period when he shot Tamir in 2014.
Cleveland city officials on Tuesday moved to discipline the officers.
Garmback was charged by city officials for failing to employ proper tactics when he operated the patrol vehicle the day Rice was shot.

While Garmback was suspended for violations related to the shooting, like failing to report his arrival to a radio dispatcher, the administrative charges leveled against Loehmann did not even mention the 2014 episode.
The shooting sparked outrage and became one of many acts of police terror that galvanized a movement for Black lives in the USA against police brutality and murder.
The penalties come more than a year after a grand jury declined to indict them in the boy's death.
"This is a politically motivated witch hunt", he added. Constance Hollinger didn't tell the officers that the man who called 911 about "a guy" pointing a gun at people said the suspect could be a juvenile and the gun might be a "fake".
Cleveland police are investigating after one person was killed Tuesday afternoon on the city's East Side.
The city agreed to pay a $6 million dollar settlement to Rice's family to settle a civil lawsuit in April 2016.
