He opened fire on an apartment over $20 of marijuana. It will cost him his freedom.

A man was murdered over $20 worth of pot. Now, it will cost the killer decades of freedom.

Last month, a North Carolina judge sentenced Malcolm Lambert to 18 to 23 in prison for the killing of Leroy Quinn in 2018. Lambert was convicted of second-degree murder and discharging a weapon into a dwelling.

On Nov. 16, 2018, Quinn was shot and killed at an apartment complex in Jacksonville, North Carolina, according to ABC 12. Lambert was arrested days later.

At a sentencing hearing, prosecutor Kelly Neal said Lambert gave Quinn $20 worth of marijuana with the idea it would be repaid.

Lambert went to Quinn’s apartment and Quinn had a BB gun, according to the Jacksonville Daily News. Quinn then shut the door in Lambert’s face. The suspect returned at nighttime and that is when he fired four shots through the window and into Lambert’s apartment.

“Twenty dollars – that’s what this whole case came down to,” Neal said, according to the Daily News. “Because of that, the defendant chose to take a firearm and shoot up an apartment complex into the back window of the apartment, and in the process Leroy Quinn lost his life over $20 of marijuana.”

Quinn was shot in the left wrist and left chest, where a bullet went through his heart and into his liver, according to the report.

The victim collapsed in the living room and was later found by his mom.

Quinn pleaded guilty to the charges using the Alford caveat, where the defendant does not admit guilt but says there is enough evidence to convict. His lawyer, Walter Paramore III, said the shooting was a one-time incident, according to the Daily News.

“I believe these were warning shots that were fired, and I do not believe that there was any premeditation,” Paramore said and the paper reported.
