Dozens march for Trayvon Martin in Roxbury

ROXBURY, Mass. (WHDH) -- Local crowds joined the calls for justice in the Trayvon Martin case on Saturday.

Dozens of supporters held a rally Saturday afternoon in Roxbury's Dudley Square, demanding the arrest of George Zimmerman.

In Florida, people are marching 42 miles from Daytona Beach to Sanford in support of Trayvon Martin's family.

A grand jury will meet next week to hear the facts, and decide if George Zimmerman should be indicted.
