Club drug Molly eyed in Harlem bar shooting

A gunman who executed a man in a busy Harlem bar was apparently high on the club drug Molly during the shooting — making him the city’s first known killer to be hopped up on the psychotic drug, police sources told The Post Thursday.

Detectives are now hunting for Dwight Reid, who vanished after allegedly firing a single bullet into the brain of Calvern Wallace, 33, the sources said.

Reid’s associates told cops he is a heavy user of the ecstasy-like drug and was likely high on it at the time of the shooting, the sources said.

Usage of the Molly, or MDMA, is on the rise in the city and was responsible for two deaths during a weekend last summer at the Electric Zoo music concert on Randalls Island.

“We believe he was on the stuff,” one law-enforcement source said.

Reid had been in PJ’s Bar at 2256 Seventh Ave. on Jan. 8 at 3:20 a.m. when he saw Wallace chatting with a woman he “had a thing for,” a law-enforcement source said.

Jealous, Reid angry asked the woman, “Why are you talking with this guy?” referring to Wallace, the source said.

“[Reid] was friends with the woman, but, in his mind, he thought they had something more,” the source said.

The men exchanged words, but before the confrontation escalated two other patrons escorted Reid outside, sources said.

Wallace looked outside the door to see if Reid had calmed down, then went back to the bar, sources said.

Minutes later, an apparently hopped up Reid walked back in and allegedly pulled a .45 caliber gun and shot Wallace in the head in front of numerous patrons, sources said.

As Wallace fell, Reid allegedly pummeled him about body, sources said.

Reid fled the bar and hasn’t been seen since.
