A relative of one of the key witnesses in the slaying of 15-year-old Christina Ann Richardson said he has moved her out of the city because he fears for her life.

As the community reels from the death of one of Baltimore?s youngest homicide victims, the family of a 16-year-old witness in the case against Lloyd Chase, 17, and Calvin Puryear, 19 ? both charged with murdering Richardson ? said she is a target of retribution.
