The Grand Rapids Police and Kent County Prosecutor have released dashcam video, 911 audio recordings, and documents of the mass shootings in Grand Rapids that left seven people dead in July.

Rodrick Dantzler killed seven people, then killed himself after a long, high-speed chase and tense hostage standoff in early July.

Here's great vid of GRPD ramming Dantzler's vehicle at Division and Fulton -

Police are giving chase to Dantzler soon after shootings. In this vid some dude falls out of the vehicle as it temporarily slows.....

You hear a lot of frustration from the officer in this vid as cursing can be heard and then an endless line of Police cruisers appear to be in the chase. Great play by play from the dispatchers etc... can be heard too. Check it out.

One more police chase vid (that breaks at times)
