Fifteen year old Johnny Lubin, Jr. was shot and killed while walking home from Miami Northwestern Senior High School on Wednesday afternoon. The 9th grader lost his life the drive-by at NW 77th Street and 14th Avenue. 

A group of mothers gathered outside the school Friday, connected by common tragedy, joint faith and community leaders to ask for an end to gun violence.

For Tesha Green, she won’t be quiet because it’s a pain she knows too well. Her daughter Precious, a Northwestern graduate, was killed just three months ago. Despite her grief, she offered support to a fellow mother who now knows her heartache.

“Her baby shot walking home from school. My baby shot walking home from the store. We cannot be quiet,” said Green.

The day before Miami-Dade County Public Schools Superintendent Alberto Carvalho visited the school to console students and teachers calling for a stop to the violence.

“This is the seventh shooting in six months, impacting a child from Northwestern Senior High School. Four of them unfortunately didn’t make it,” said Carvalho on Thursday. “The senseless..cowardly attacks that are chipping away at the soul of our community must come to an end.”

He went on to say, “There’s got to be a disruption to the code of silence that exists in these communities. There are people out there who know who did this. And they have got to speak out.”

It’s a call that is ringing out through the community and other local leaders are worried about.

“Our concern as community leaders is that we need to put an end to this. This has got to stop now or we are going to have a very bloody Christmas and a very bloody Thanksgiving and an even bloodier New Year,” said Rev. Eric Readon of the New Beginning Missionary Baptist Church of Miami Gardens .

Meantime, Lubin’s mother Julie Examar  mourns the loss of her son to what she calls foolish acts.

“We need to stop all this foolishness, killing innocent teenagers for no reason,” said Examar. “I want to say to the person who did this that they need to come forward.”

Police say they continue to search for answers, not just to solve these crimes, but to stop more from occurring.
