Sandra Bland was frustrated and "at a loss for words" in a short voicemail she left a friend days before her death.
According to ABC News, Houston station KTRK obtained the 22-second message left for a Texas woman Bland stayed with before being arrested.
I'm still just at a loss for words honestly at this whole process. How did switching lanes with no signal turn into all of this, I don't even know.
This was one of three phone calls Bland, 28, made after her court hearing on July 11.
The others were to her sister and a bail bondsman who Bland reportedly spoke to about posting bail.
The alleged suicide evoked immense suspicion because Bland was about to start a new job, had inquired about being bailed out of jail and, as friends and family members say, did not appear depressed in the days before her arrest.
Cannon Lambert, an attorney for the family, told CBS News,
We know for a certainty that when she went into that jail, she was ecstatic. She had left messages with her loved ones and that just does not jive with someone who would take her own life.
Yesterday, however, it was revealed shortly after her arrest, Bland told a deputy at the prison she had attempted suicide in 2014 after losing a baby.
In a video posted to Facebook last March, she also said she was suffering from depression and post-traumatic stress disorder.
But roughly three hours after being taken into custody, Bland told a prison worker she was not contemplating taking her life.
The death is still being investigated as a murder.
