A 37-year-old bipolar and schizophrenic woman died after police slammed her to the pavement outside her family's home, her brother said.

Tanesha Anderson was pronounced dead at Cleveland Clinic early Thursday after an altercation with officers nearly two hours earlier on the 1300 block of Ansel Road.

"They killed my sister," her 40-year-old brother Joell Anderson said with welling eyes in his living room Thursday night. "I watched it."
