An inmate who was released by mistake a week earlier was returned to the Shelby County jail Thursday following the third such blunder by the Sheriff&8217;s Office since September.

Inmate Brian Russell Dorminey was located at a residence in the 1000 block of Rene Road in Columbiana where he was taken into custody without incident, according to a news release by the Shelby County Sheriff&8217;s Office.

Dorminey had been transported from the Shelby County Jail to Calera on Nov. 2 to appear in court on municipal charges. He was granted a court-ordered release from Calera on their charges and was subsequently released from the Shelby County Jail.

Separate state charges for which Dorminey had not made proper bonds were discovered &8220;within moments,&8221; according to the Sheriff&8217;s Office.

Those charges included failure to appear in court on a variety of forgery and drug related charges with a total bond of $145,500.

Despite an immediate search, Dorminey wasn&8217;t located until a week later, when Sheriff&8217;s Office investigators pinpointed his whereabouts at the Columbiana residence.

&8220;This was an unacceptable mistake by our corrections staff and appropriate corrective actions will be taken after the internal investigation is complete,&8221; said Capt. Chris Corbell.

Two other inmates were mistakenly released from the Shelby County Jail on Sept. 1.

That incident, referred to by Sheriff&8217;s officials as the &8220;first accidental release that this administration can recall,&8221; was attributed to a data entry error.

Both inmates, Chevor Brigades Hines and Tammy Jean Matlock, were returned to custody a week later.

The Shelby County Jail books approximately 15,000 inmates per year.

No additional charges will be preferred on the inmates involved in the accidental release cases, Sheriff&8217;s officials said
