A recruit fired from the Orleans Parish Sheriff’s Office in late May was arrested this week after she returned to the Orleans Parish Prison in full uniform and worked a 12-hour shift, authorities said.

Dariyan Octave, 21, who had worked at the Sheriff’s Office about three months before she was fired, was booked Wednesday evening on counts of trespassing and impersonating an officer. A magistrate judge ordered her held in Orleans Parish Prison in lieu of $5,000 bail.

The arrest raised fresh questions about security at the jail, particularly in light of the allegation that Octave managed to access a tier at the jail’s Conchetta facility where her boyfriend was being housed.

Authorities were investigating whether Octave tried to smuggle a cellphone to the inmate, whom she had been dating before his incarceration, according to sources familiar with the case.

A warrant for Octave’s arrest said it was “unknown if she attempted to pass contraband to her boyfriend,” a prosecutor said in court Thursday.

One source said Octave’s name still had not been removed from the Sheriff’s Office electronic list of employees as of late Wednesday. Still, it remained unclear how she managed to work an entire shift beginning Monday without any supervisors taking note of her unauthorized presence.

Octave was taken into custody at 5:45 p.m. Wednesday in New Orleans East.

Octave’s mother, who also works at the Sheriff’s Office but declined to give her name, said Thursday she had no idea her daughter had been fired. She said her daughter had spoken with Sheriff Marlin Gusman, who supposedly told her she was free to return to work. The sheriff denied that claim.

“I’m just blown by this,” Octave’s mother said after attending her daughter’s initial appearance in Magistrate Court. “I don’t even know where I go from here.”

Karen Orzechowski, a public defender who represented Octave at the hearing, said her client understood she had been disciplined by the Sheriff’s Office but did not believe she had been terminated.

She said Octave has a 1-year-old child.

The Sheriff’s Office issued a news release about Octave’s arrest late Wednesday night, but a spokesman did not respond to questions Thursday, including an inquiry about why Octave was fired.

A few weeks before her dismissal, court documents show, Octave had been held in contempt of court in Jefferson Parish for missing an arraignment on a misdemeanor theft charge. She and a co-defendant, Terrance C. Washington, had been accused in December of shoplifting from the Macy’s store at Lakeside Shopping Center in Metairie. An arrest report said the couple tried to steal about $575 worth of merchandise from the store.

Octave previously worked about eight months for the Jefferson Parish Sheriff’s Office. A spokesman said she had no disciplinary history with the agency and had been assigned to the 911 center.
