Brother of Oklahoma City Thunder G Dion Waiters killed

Guard Dion Waiters left the Oklahoma City Thunder to be with his family after learning his younger brother was killed in Philadelphia on Tuesday.

Waiters was not with the team for Wednesday night's game against the Los Angeles Clippers as he mourned the death of his brother.

According to reports, Waiters' brother was one of six people killed on Tuesday in three separate acts of violence. No arrests have been made.

Waiters, a native of Philadelphia, posted on Instagram about the death of his brother: "The call I just got about my lil brother wasn't expecting this s---.....crushed my heart I never question why.... But this hurt.... I promise I got Yu mark my word..... Love Yu kid... r.i.p."

Waiters is averaging 9.6 points, 2.7 rebounds and 1.9 assists in 63 games (12 starts) this season.

"We feel for Dion, man," Thunder star forward Kevin Durant told ESPN.com. "He's our brother and it's tough for anyone to go through that, and we have his back on everything. He's got our love and support throughout it all and he knows we're here for him."

Thunder general manager Sam Presti said, "We were saddened to hear the news of the passing of Dion's brother, and he has our full support. Dion and his family are in our thoughts and prayers during this difficult time."

The Thunder organization has dealt with two other tragedies in recent weeks.

Thunder assistant coach Monty Williams' wife was killed in a multicar accident on Feb. 9 and part owner Aubrey McClendon died in a single-car crash on March 2.

"That's how life throws it at you sometimes," Durant said. "Definitely unfortunate to go through it, but the only thing we can do is continue to stick together as an organization, as a family and help everyone through this. That's what brings everyone together. It's definitely tough for all three families, but they have our support and our love."
