SACRAMENTO (CBS13) — A grieving family is looking for answers after a young mother was killed in a South Sacramento shooting.

Erica Frazier, 27, is dead after four people, including a little boy, were shot Friday at a South Sacramento apartment complex.

CBS13 has learned the shooting was targeted, and that Frazier and the 4-year-old boy were both bystanders. The family said Frazier was at the apartment complex off of Stockton Boulevard by chance.

She was planning on stopping by for a birthday party at a friends house. In an instant, her life was cut short and we’re told she was not the intended target.

“Our family needs peace because we need to find out who did this to my sister,” says Frazier’s sister Zasha Hodge.

Hodge sat alongside an extended family inside the house in Oak Park Frazier had just bought for herself and her two daughters.

They looked at photos of the 27-year-old, they say her life was just beginning.

“She wasn’t involved in violence, I could call and talk to her whenever,” said her sister Cynthia.
