A man police believe may be connected with the slaying of rapper Stack Bundles was found dead in vacant house in Queens, New York on Monday (June 18).

According to the New York Daily News, 20-year-old aspiring rapper Charles White was killed execution-style. Cops says they found him dead on a sofa at around 12:20 a.m. with a pillow over his head, a gunshot wound to the leg and two bullet wounds behind his ear.

Police suspect the murder was in retaliation for the Stack Bundles killing, who was found dead in the lobby of his Far Rockaway residence on June 11.

Police also said the 20-year-old murder suspect may have gone to Virginia, where he lived, right after Bundles’ murder, but returned to New York last Saturday (June 16) with his friend Kelvin Brown, 27.

Brown had reportedly just left the home when White was shot. But after hearing the shots, he ran back to the house and called police. The house White was shot in has been on sale for months and was vacant.

A man, who lived in the neighborhood and wished to remain anonymous, said he saw three men on the stoop of the home Sunday night, describing them as being very polite. “One of them said Happy Father’s Day to me,” the man said.

No arrests have been made in the shooting, but cops are continuing to investigate.
