Ferber was last seen departing from her nightclub, The Underground Railroad, in Morgantown, West Virginia on April 28, 1988. The business was located in the 100 block of Pleasant Street at the time. Ferber left her vehicle, purse and other personal belongings at her residence. There were rumors that Ferber had traveled to Florida or Jamaica after her disappearance, but authorities were unable to find any evidence to confirm the speculation. She has never been heard from again.

Ferber opened The Underground Railroad in 1982. The establishment reflected her liberal political views and taste in music, all the while promoting equality. Ferber's friends and employees kept the bar open for a year after her disappearance, but The Underground Railroad was eventually sold to another owner.

Ferber's family members reside in Maryland and New York. She lived in Massachusetts before relocating to West Virginia in the 1970s.

Some agencies may list April 25, 1988 as the date of Ferber's disappearance.
