SAN FRANCISCO (KCBS)—A successful gun buyback event in San Francisco’s Mission District on Thursday night was the first in the U.S. to be partly-funded though a crowdsourcing non-profit.

GunByGun.org collected $13,000 online from 160 people to help fund the buyback, which collected 157 firearms last night at a parking lot on 22nd and Capp Streets in the Mission District.
