Freddie Gray, a Baltimore man injured during an arrest by Baltimore police last week, died Sunday at Shock Trauma, prompting protests by city residents and out-of-town activists and promises from city officials for a thorough investigation.

Gray, 25, died a week after he suffered a broken vertabra after being arrested near Gilmor Homes in Sandtown-Winchester.

Police have not given a cause for Gray’s injuries or specified why he was arrested, citing an investigation into the incident. Officials are expected to look into any criminal conduct by Gray and whether criminal charges against officers are warranted.

As a family attorney raised questions about the circumstances surrounding Gray’s death, his stepfather, Richard Shipley, said relatives were too distraught to talk.

“He’s gone,” Shipley said. “What else is there to say?”

At a news conference, Mayor Stephanie Rawlings-Blake and Police Commissioner Anthony W. Batts said they are committed to providing the public with information about the circumstances of Gray’s death.

“I understand the frustration of the community and I take very seriously my obligation of transparency,” Rawlings-Blake said. “However we also have to balance that with our obligation to ensure a proper and thorough investigation is undertaken. Therefore we have to move forward in a responsible way to determine all the facts of this incident so that we can provide the community with answers.”

More than 100 protesters have gathered for two days outside the Western District station, demanding answers about what happened to Gray.
