While many mourn the death of George Floyd after he was killed by Minneapolis police on Monday, former NBA veteran Stephen Jackson is among those who are especially devastated by the tragedy.

Jackson expressed his sorrow in a series of Instagram posts, saying "this is what I gotta wake up to."

"Twin. I promise I won't let this BS ride. Already talked to @shaunking," the former NBA forward wrote in the caption of one video. "Anybody from Houston/Cuney Homes u know this was my brother. Can't let this ride. All hands on deck. Rest Easy Twin."
