VIDEO: Gangbanger murder at Queen’s Subway. This is why we must be vigilant and armed.

Investigators have now charged Ramiro Gutierrez, 26, who police say is a member of the violent MS-13 street gang, with murder, gang assault and weapons possession for the bloody Sunday afternoon shooting, where victim Abel Mosso, 20, was shot repeatedly in the face.

The murder was the first killing on the subway in more than a year. Six shots were fired. The victim was struck in the head and died at the 90th Street-Elmhurst Avenue station, where the altercation spilled out of a Manhattan-bound 7 train just before 1p.m.

And someone caught it on camera.
