Steve, from further down in the article:
Timpa called 911 on Aug. 10, 2016, from the parking lot of a Dallas porn store, saying he was afraid and needed help. He told a dispatcher he suffered from schizophrenia and depression and was off his prescription medication. The News first reported Timpa’s death in a 2017 investigation that showed Dallas police refused to say how a man who had called 911 for help ended up dead. …
He had already been handcuffed by a private security guard before police arrived. He never threatens to hurt or kill the police.
