‘This is street justice’: Bronx mother, 45, is shot dead through peephole by masked gunman ‘targeting her son who is on trial for murder’

A mother at home with her 14-year-old in the Bronx was slain by a bullet through her door’s peephole Saturday night.

Wendy Martinez, 45, went to her door in her Concourse Village apartment sometime around 9.45pm when she was shot in the head through by a masked gunman, the New York Post reported.

Her teenage son called 911 from a closet to alert authorities, but she was pronounced dead at the scene.

Martinez, an employee at Lincoln Medical Center and Red Sox fan living in the Bronx, likely was not the intended target, according to police.

Shoot through the peephole.

Doors are not bullet proof.

There are plenty of video doorbells on the market that can be had for around $100.

Answering the door from another room is another  layer of personal security that is easy and cheap to add to you life.
