The shooting occurred at an upscale apartment complex called South Side Flats not far from downtown Dallas, NBC reported. However, it was the wrong apartment and when the police officer ran into a man that she did not recognise, she shot him.
The chief declined to speculate as to whether fatigue or other factors, including race, may have contributed to the shooting. He described Jean as an "amazing individual" and said that "if the grand jury deems necessary, this officer should have to answer for her actions in a court of law in Dallas County".
Jean had graduated from a private Christian college in Arkansas in 2016 and had since been working at the accounting firm PricewaterhouseCoopers in Dallas.
"I don't want to judge her", Jean said.
Hall said at a press conference, which you can watch above: "My condolences to the Botham Shem Jean family".
Afamily has been plunged into mourning following the horrific and untimely death of their kin, Botham Shem Jean, a Saint Lucian man who resided in Dallas, Texas. Clark, 22, was fatally shot earlier this year by officers in the backyard of his grandparents' home in Sacramento, California.
According to the university, Botham frequently led worship for chapel and for campus events. She also said the Texas Rangers will conduct an independent investigation.
Hall said police drew a blood sample from the officer to test for drugs and alcohol. Police said she was in full uniform when she walked into an apartment she thought was her own and fired her weapon at the man inside.
Allison also revealed that she was visiting NY when she received a call informing her that Botham had been killed in his own apartment.
Police Chief U. Renee Hall said the day after the shooting that her department was seeking manslaughter charges against Guyger. "However, as we continued the investigation it became clear that we were dealing with what appears to be much of a very unique situation", Hall said.
"I won't go into that information right now", said Sgt. Warren Mitchell, a Dallas police spokesman. "We understand the concern of this community".
"This is a awful tragedy", Jean's employer said.

His uncle Ignatius Jean said relatives were devastated by his death, calling his nephew a "brilliant" man of "impeccable character".
Hall said she hopes the investigation can bring clarity to the family.
