A Brooklyn man who was shot over three decades ago but survived recently died of those very injuries — and officials are now calling his death a murder, police said Friday.

Billy Yee, 59, died of complications from four bullet wounds in his torso from shots that were squeezed off by Stanley Cho, 58, back in 1982 during a Brooklyn Heights drug deal gone wrong, police said.

Yee, who was 26 at the time, was sitting in a parked car on Sands Street under the Brooklyn-Queens Expressway about 2 a.m. June 14 when Cho, who was 25, struck him twice in the back, once in the spine and once in his right side, authorities said.

Cho was arrested less than a month later and charged with assault and criminal possession of a weapon, cops said.

Yee was rushed to Cumberland Hospital, where he made a full recovery — almost.

After Yee died on Oct. 2 of this year, an autopsy carried out by the Medical Examiner’s Office deemed his death a homicide, authorities said.

The Brooklyn District Attorney’s Office will determine if Cho will be charged for Yee’s slaying 33 years ago, police said.
