The female cop who shot her neighbor and said she had entered his apartment thinking it was her own has been arrested and charged with manslaughter.

Dallas Police Officer Amber Renee Guyger, 30, was booked into Kaufman County Jail at 7.20pm on Sunday on a charge of manslaughter in the Thursday shooting of 26-year-old Botham Jean, jail records show.

Guyger posted bond of $300,000 and was released by 8.30pm. Kaufman deputies allowed her to leave by the rear of the jail, avoiding the gathered press, rather than the front of the building as is typical for bonded inmates, according to local reports.

Kaufman County is directly southeast of Dallas County, where the shooting occurred.

In Texas, the penalty for a manslaughter conviction is between two and 20 years in prison.

The Texas Rangers, who took over the investigation on Friday, said the investigation is ongoing and declined to offer further information about the case. The Rangers, a law enforcement group equivalent to state police, ran the investigation to avoid the appearance of any potential bias, Dallas Police Chief Renee Hall said at a press conference on Friday.

Earlier on Sunday, Jean’s mother Allison and 15-year-old brother Grant mourned his death at an emotional prayer service at Dallas West Church of Christ.

The congregation paid tribute to Jean, a consultant who was active in the church’s ministry service, by signing his favorite hymn: My God Is Real.

Later Sunday, the family held a press conference at 7pm demanding Guyger’s arrest, apparently unaware that she had already been arrested in Kaufman County at 6.37pm and was en route to booking.

Jean’s family has hired attorney Benjamin Crump, who is best known for representing the families of Trayvon Martin and Michael Brown.

The perplexing shooting unfolded at about 9.59pm on Thursday, when Guyger had just gotten off of a full shift.

According to Guyger, she mistakenly entered the wrong apartment in the complex where she lived, thinking it was her home, and had some kind of confrontation with Jean that ended with her shooting the man with her service weapon.

Guyger, who was in uniform, immediately called 911 to report that she had been involved in a shooting, investigators said.

Police and paramedics administered aid at the scene, and Jean was rushed to an area hospital, where he was declared dead.

The immediate aftermath of the shooting was captured in footage posted by a neighbor, showing a female uniformed officer crying into her phone on a walkway of the apartment block.

She is heard screaming ‘oh God!’ into the phone before she dashes away out of view.

Moments later, the victim is pulled past on a gurney as medics desperately try to revive him. Four officers follow directly behind and another runs to catch up.
