In early 2011, weeks after her 24th birthday, Bianca Chanel Green dropped off her son with relatives — then vanished.
On March 25, the Wayne County Community College nursing student from Romulus, who worked at a restaurant in Detroit Metro Airport, told her mother she was going home to rest.
The next day, Lisa Greene was alerted by her cousin, Tawana Butler, who saw a Facebook message from Green saying she planned on leaving.
Greene tried calling her daughter's cell phone and when she didn't respond, she texted her.
In a series of texts, Green told her mother she was pregnant, "can't take it anymore," and planned to travel by bus to the South. She also asked that her son and car note be taken care of.
"She said she would call me when she got to her destination — and she never did," Greene said.
Greene again tried reaching her daughter, who only texted back: "I love you." That was the last contact anyone in her family had.
Subsequent texts and calls went unreturned. Greene was able to get a copy of her daughter's credit union statement, which showed an Internet transaction in Georgia, but no other activity, she said.
The case remains open, Romulus Police Detective Kelly Fragodt said.
Seeking exposure out of state, Greene reached the nonprofit Black & Missing Foundation, which interviewed her and relatives for a cable television story that aired last year. Police followed up on tips, but nothing was fruitful.
Greene is pursuing help with other groups, and wants to travel as far as she can afford.
What drives her is the possibility of finding answers, she said. "How can you stop looking for your child?"
In April, Green's son turned 6. When he asks about his mother, Greene is unsure what to tell him.
Meanwhile, her absence is felt elsewhere.
"It affects us daily — whether it's Christmas or Thanksgiving," Butler said. "No matter what occasion it is, we miss her. Our family is close knit. … Anytime we have a family gathering, it's obvious she's not there."
This spring, Greene was heartened by the discovery in Cleveland of Amanda Berry, Gina DeJesus and Michelle Knight, who had been reported missing for years.
"It's very hopeful and encouraging, but at the same time … I would hate to think she's out there somewhere being locked up, tortured," she said.
