The Cleveland officer who said he was following police training protocol when he shot and killed Tamir Rice wants his job back.

Attorneys for Timothy Loehmann and for the City of Cleveland head to arbitration on Wednesday.

Loehmann was fired for what Cleveland attorneys say was essentially lying on his application. Something they never knew until after Tamir Rice was shot.

November 22, 2014. It was the story of a 12-year-old shot heard round the world.

An epicenter at Cudell Recreation Center on Cleveland's west side that would prompt widespread protests.

Loehmann was one of the Cleveland cops responding to calls of what they thought was an 18-year-old pointing a gun at people in the park outside Cudell.

"It was that quick. I was about like this and that's when I had to fire two shots and attempt to gain cover," Loehmann explained as he reenacted the position he took before he fired.

It turned out to be a realistic looking pellet gun.

Loehmann said all along he thought Rice was reaching for a gun in his waistband.

"I believed there was a threat to me and my partner. That he was acting to kill us or harm us,” said Loehmann.

Here's how the timeline played out:

December 2015.

No indictment.

A grand jury decides no criminal charges for Loehmann.

April 2016.

City of Cleveland pays Tamir Rice's family $6 million to settle a federal lawsuit.

May 2017.

The City of Cleveland fires Loehmann for leaving out important information out on his 2013 application to be a Cleveland cop.

In a previous job, Independence police supervisors wanted to fire him, citing instances of insubordination, lying and an "inability to emotionally function.".

Loehmann was allowed to resign.

He was on the Cleveland police force fewer than eight months, and was still on probation when Rice was shot.
