Superintendent takes to Twitter, criticizes 'cowardly' silence after shooting

Student, 18, shot in back; man, 19, grazed in head, wrist

MIAMI – When news broke that a Miami-Dade County student was shot in the back Thursday night, Superintendent Alberto Carvalho took to Twitter. 

"Cowardly gun violence injures one more teenager in the streets of Miami," he wrote in part. 

The student, an unidentified 18-year-old man, was shot in the back near Northwest 53th Street and Northwest Seventh Avenue, Miami-Dade police said. 

Another man, 19, was grazed in the head and wrist. 

In another tweet, Carvalho called for the community to speak out against gun violence. 

"Community violence will prevail to the extent the cowardly code of silence overpowers the courage to speak up about what is seen and known," he wrote. 

A woman who lives in the area told Local 10 News that children often ride dirt bikes in the neighborhood, so she is now worried for their safety.

A motive for the shooting is unknown.

Anyone with information is asked to call Miami-Dade Crime Stoppers at 305-471-TIPS.
