Yes from what I read shooter had a long gun. IMHO
Police have confirmed that the suspect is dead, his motive or identity have not yet been confirmed according to Dayton PDs official Twitter.
I found most of the more informative links (including DPDs) via the Heavy.com article as posted upthread:
Dayton Shooting Videos & Photos from the Scene [GRAPHIC] | Heavy.com
Local reporter Derek Myers (of note he is not with a major news org so not verified), tweeted several videos live from the scene after the shooting sheikh scene of first responders, etc. Some small other details reported that he had not yet verified with police, if interested follow link to Myers Twitter via heavy.com.(Content warning: while his don’t seem to be as graphic as others but do be aware with all of the videos out there)
Also at the link, a witness describes the killer wearing noise cancelling headphones
"James was parked in front of Ned Peppers bar when the incident happened and described the incident and the suspect “We had an active shooter with an AR 15.
Came up with an AR 15 with a vest on and ear muffs and just started blowing bullets everywhere…there are casualties everywhere. Outside Ned Peppers, there were at least eight victims. I don’t know how many people they took away from other locations… it’s awful.” He says he saw at least 8 dead victims in front of the bar."
Is there some sort of equipment checklist or tips these guys share online?
Additionally, link to the NYTs article which reports 10 dead (including suspect) and at least 16 wounded.
