CLEVELAND, Ohio -- Timothy Loehmann, the rookie police officer who shot and killed 12-year-old Tamir Rice, was fired Tuesday.

His partner, Frank Garmback, who pulled his cruiser within feet of the young boy, was suspended for 10 days without pay.

Loehmann was fired not for shooting Tamir, but for lying on his application with the Cleveland police department. He was also in his probationary period as a Cleveland officer giving the department more flexibility in letting him go, Cleveland Public Safety Director Michael McGrath said.

Cleveland Police Patrolmen's Association president Steve Loomis said he will address the disciplinary measures at a 3 p.m. news conference.

Loehmann was a Cleveland police officer for less than eight months before the November 2014. He shot Tamir in less than three seconds after arriving at Cudell Recreation Center.

The announcement effectively closes the door on a more than two-year investigation into what is widely considered one of the most high-profile police-involved shootings in Cleveland's history.

Tamir's death amid a series of other controversial, high-profile police-involved shootings across the country and sparked dozens of protests in Cleveland. The public outrage over the shooting heightened after grand jury declined to indict either officer.

A disciplinary letter released in January specifically says that Loehmann lied about how his short stint at the Independence Police Department ended.

Loehmann was allowed to resign from the Independence department after six months following a series of incidents where supervisors determined he was unfit to be a police officer.

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.

Cleveland officials said in the letter that Loehmann was supposed to disclose that information. He was also supposed to say in his application that he failed a 2009 written exam when applying to work as an officer in Maple Heights. Loehmann never mentioned the Maple Heights test.

Garmback's disciplinary letter said he used improper tactics when driving to the rec center, which put Loehmann in danger.

Two others have been disciplined in the case: the 911 call taker, Constance Hollinger, and officer William Cunningham, who was working was working off-duty at the rec center without permission. He received a two-day suspension without pay.

Hollinger was suspended eight days without pay for failing to relay critical information to a dispatcher, Beth Mandl, who sent Garmback and Loehmann to the rec center.

Hollinger failed to tell Mandl that the 911 caller told her that Tamir was "probably a child" and that that the airsoft pellet gun he had was "probably fake." Mandl told Garmback and Loehmann to investigate a report of a "guy with a gun" scaring people outside the center.

Then-Cuyahoga County Prosecutor Timothy J. McGinty said Hollinger's omission was a crucial mistake that directly impacted how the officers handled the call. McGinty said the shooting might have been avoided if the information was properly relayed to the officers.

The city paid a $6 million settlement to Tamir's family, which is likely the largest settlement the city has paid in a police-shooting case.

A review committee comprised of city officials that took the place of a normal internal affairs investigation found that neither officer violated any police policies.

The panel, called the Critical Incident Response Committee, concluded that neither Garmback, nor Loehmann violated any police policies at the time of the incident.

They concluded that Garmback took a path towards Tamir that other officers regularly used, that he wasn't driving too fast and that he tried to stop sooner than he did, but skidded on the wet grass.

That put Loehmann in a position where he got out of the cruiser and was directly in line with Tamir. Dispatcher Constance Hollinger had told the officers that someone had a gun at the park, but failed to tell them the initial 911 caller said that it was "probably a juvenile" and that the gun was "probably fake."
