Evidence from an autopsy on Sandra Bland, the black woman found hanging dead in a Texas jail days after a traffic stop, supports the medical examiner¡¯s initial ruling of suicide, a county prosecutor told reporters on Thursday.

The preliminary results also found high levels of marijuana in Bland¡¯s system, although officials are seeking additional tests to confirm when and how much she might have smoked or swallowed, Waller County Assistant District Attorney Warren Diepraam said.

¡°The evidence that we reviewed up to this point supports those findings,¡± he said of the initial suicide ruling.
