Alexandra Pyle, who was in the Waller County Jail in Texas due to unpaid parking tickets, said she was in a cell opposite Bland's.
"She seemed really distraught," Pyle said. "But I don’t know if I can say that was suicidal."
But she added that she was "positive" that Bland took her own life, and that the 28-year-old woman showed her scratches she had on her wrist.

"I don't think the guards did anything," Pyle said. "She wasn't causing a ruckus or anything, so I don't see why the guards would do anything to her. She was quiet."
Bland's mother, Geneva Reed-Veal, has also spoken out, telling MSNBC's Al Shparton that her daughter was in a good mood before her death. She said she was excited about starting a new job.
"Her spirits were lifted," she said. "She was excited."
