A Florida hairstylist has been missing over a week and with authorities feeling she’s likely dead, they’ve named her co-worker a suspect in her disappearance.

New York Post reports that a family member reported Joleen Cummings (pictured right), 34, missing on May 13. She was last seen leaving the Tangles Hair Salon in Fernandina Beach. She left the salon at around 5 p.m. on May 12.

On Tuesday afternoon, Sheriff Bill Leeper announced that authorities have a suspect in custody in connection with Cummings’ disappearance. The suspect was identified as Jennifer Sybert (pictured left), 50, a co-worker that had been working at the hair salon with Cummings for around a month.

Although he didn’t go into details, Leeper said that detectives uncovered information “which leads us to believe that Joleen is not alive.”

The suspect was the last person to Cummings after the pair worked at the salon, according to News4Jax. When Cummings failed to pick up her three kids from her former husband, she was reported missing. On May 14, authorities went to the salon to interview Sybert but she left before they could talk to her. Another co-worker told police that Sybert pulled into the parking to report for work, but when she learned police wanted to speak with her, she left.

The following day, authorities found Cummings’ SUV abandoned close to a local Home Deport store. Surveillance camera reportedly captured Sybert parking Cummings’ vehicle a little after 1 a.m. on Sunday. Sybert got out of the driver’s side of the SUV but Cummings never emerged. According to an affidavit, Sybert then walked to the nearby Gates gas station, where she got into a taxi cab.

On May 16, police located Sybert sleeping inside a black Kia Soul at a rest area off of Interstate 95 in St. John’s County. She was arrested and charged with grand theft auto, based on the footage of her driving the victim’s car. Police also noted she had scratches on one hand and one eye.

Further, the FBI charged Sybert with possession of a counterfeit passport after they determined she was using a fake social security number.

Days before she was reported missing, Cummings was in a domestic dispute with her ex-boyfriend, Jason Gee. Gee was arrested on a probation violation on May 15 but has not been named a suspect in Cummings’ disappearance.

Anyone with information regarding the case is urged to contact the contact the Nassau County Sheriff’s Office at 904-548-4005 or First Coast Crime Stoppers at 1-866-845-TIPS.
