Last Friday, I wrote about the extended surveillance video that captured the killing of Tamir Rice in a Cleveland park by police officers. In that post, I wrote, “The video has no sound, but it is not hard to imagine her screaming her brother’s name and pleading for answers about what happened.” Well, I didn’t have to imagine for long.

A Twitter follower sent me a link to an article that included another video obtained by NBCNews.com. What the 95 seconds captured by Treyvon Osborn on his cellphone Nov. 22 lacks in quality, it more than makes up for in sound. The shrieking alone will tear your heart out.
