The sister of New York Knicks small forward Reggie Bullock was fatally shot in Baltimore on Monday night, authorities said.

According to police, Keiosha Moore, 22, was shot in the chest around 7:48 p.m., WJZ reported. Moore was able to walk to an area hospital but died of her wound, the television station reported.

It is not the first time Bullock has lost a sister to tragedy. On July 16, 2014, Mia Henderson, a 26-year-old transgender woman, was fatally stabbed in a Baltimore alley, The Sun of Baltimore reported.

Bullock shared his grief in an Instagram post.

"I never felt so BROKEN in my life! My 2 queens, my 2 that go super HARD FOR ME!" Bullock wrote next to a photo of Moore.

The Knicks posted condolences on Twitter to Bullock and teammate Dennis Smith Jr. on Tuesday. Smith's stepmother died suddenly Sunday.

Bullock, who was born in Baltimore, became active in the LGBTQ community after Henderson's death, The Sun reported.
