Tracy Walker says he still can’t make sense of it.

He has tried for months to understand why his cousin Ahmaud Arbery was shot and killed while jogging in broad daylight in their hometown of Brunswick, Georgia.

The Detroit Lions safety says he has questions he has been trying to answer.

When the video of his 25-year-old cousin’s killing appeared online, Walker says, he watched it “no exaggeration, over 100 times,” each time leaving him more frustrated, more angry and more “pissed off.”

After the video appeared last week, Gregory McMichael and his son, Travis McMichael, were arrested and charged with murder and aggravated assault more than two months after Arbery was killed on Feb. 23. Federal prosecutors also are considering hate-crime charges that would allow for a separate case in federal court.
