Rochester's mayor plans to shut down entire streets that he says have been overrun by violent crime as part of the city's gun violence state of emergency.

Malik Evans said Thursday he'll extend the emergency declaration again, making it a full year that the city has worked under it.

The declaration provides executive authority that gives the mayor the ability to cordon off entire sections of neighborhoods where gunfire, shots into homes and fires, which police say are often perpetrated by youth, have turned parts of neighborhoods into danger zones.

Evans has yet to offer details on what that would look like.

The mayor spoke publicly after police say three teens were shot and wounded Wednesday evening near Genesee Street and Samuel McCree Way. According to investigators, it unfolded after an argument broke out following a car crash. One of the vehicles involved was stolen, police say.

The state of emergency, which also provides authorities with ways to shut down businesses linked to violent crime, went into effect last July.
