Amid tears and cries for justice, demonstrators poured into the streets of Baltimore carrying signs emblazoned with the name of a man who died from a spinal injury he suffered while in police custody. Tuesday's demonstration marked the beginning of a week of protests and rallies planned across the city.

The Justice Department said earlier in the day that it has opened a civil rights investigation into the death of Freddie Gray, a 25-year-old black man who suffered a fatal spinal-cord injury under mysterious circumstances after he was handcuffed and put in the back of a police van.

At the site of Gray's arrest, more than a thousand demonstrators gathered to remember Gray, who friends and relatives say was kind, funny and generous, and call for police reform.
