A makeshift memorial sprouted up outside the apartment building, and friends and relatives of the victims gathered for a march and rally calling for an end to violence.

"Loving, caring, very sweet, always full of life," Free's mother, Rhonda Valentine-Free, told ABC-TV. "It's sad. They just took them. They just took them away."
