Amber Guyger, 31, was convicted of murder on Tuesday after she shot dead her black neighbor Botham Jean, 26, in his Dallas apartment

A jury reached the unanimous verdict in the high-profile trial after six days 

The murder charge brings a prison sentence of between five and 99 years

Loud cheers erupted in the courtroom after the judge read out the jury's verdict

Guyger sat alone, weeping, at the defense table as a sheriff's deputy appeared to stroke and fix her hair  

Guyger, a four-year veteran with Dallas Police, was off duty but still in uniform when she fatally shot Jean in his home on the evening of September 6, 2018

She told investigators that after a 13.5 hour shift she mistakenly entered the wrong apartment and shot Jean thinking he was an intruder

Prosecutors argued that Guyger should have known she was on the wrong floor and questioned why she didn't radio in for help

They said she had non-lethal tools on her service belt at the time, including a stun gun and pepper spray

Her defense attorneys tried to argue that Guyger fired her gun in self-defense based on the belief that Jean was a burglar
