Roughly three weeks after Stepha Henry vanished from a relative’s Florida home, police and family members are refusing to give up the search for the 22-year-old woman.

Henry, of Brooklyn, N.Y. was last seen on May 29, climbing into a dark sedan with an unknown acquaintance, telling relatives she was going to Club Peppers in Fort Lauderdale. Miami-Dade County police have examined abandoned cars and traced signals from her cell phone, which now goes straight to voicemail. At this time, police don’t know if foul play was involved in her disappearance.

The woman's parents, Steve and Sylvia Henry, traveled to Florida the week she disappeared and are still there, posting fliers and looking for answers.

“I think that she's being held against her will somewhere out there. And I pray God that someone have mercy on her and let her go, because she's a bright girl. She's very intelligent. She has all of her plans and career goals set, and she's about to accomplish them,” the woman’s mother, Sylvia Henry, told FOX News.

Stepha is black, 5-foot-2, 110 pounds, brown eyes and has red hair that falls just past her shoulders. She was last seen wearing a black dress with a white tank top underneath. She is an honors graduate of John Jay College of Criminal Justice, is fascinated by criminal cases and wanted to be a lawyer, relatives said.

"She always wanted to be the lady Johnnie Cochran," Stepha’s aunt, Daffodil Samuel told the Associated Press on Sunday.

Until Henry is found, family members are holding out hope, but it hasn’t been easy.

"It's sleepless nights," Samuel said. "It's being hungry and can't eat. It's fasting and constant prayer."
