A man was fatally shot in the face after he tried scoring some weed in a Bronx apartment Sunday night, police sources said.

Jonathan Tuck, 25, was a quarter-mile from home, visiting an apartment on Washington Ave. near E. 185th St. in Belmont, when he got into an argument with someone inside, according to sources.

It’s unclear if the pot deal sparked the beef, but it ended with Tuck shot in the face, the sources added.

Medics took Tuck to St. Barnabas Hospital, where he died.

Cops have taken a 34-year-old man into custody for questioning, though they’re still sorting out if he was the shooter, sources said.
