Sandra Bland voicemail message before jail death

A Texas woman who police say took her own life while in custody, phoned a friend from jail to say she was "at a loss" over her arrest.

In a voicemail obtained by the US TV network ABC, Sandra Bland said she could not understand why a traffic violation had led to her detention.

The 28-year-old was arrested after a confrontation with the officer who had pulled her over. She was found dead three days later.
