Speaking through a translator, Zhi He Kuang said he wants others to know what happened, in fear the suspect will be released, and wants to make sure his mother did not have to "die for nothing."

Shan says her aunt was a quiet caretaker of her grandmother for about 10 years and was looking forward to retirement.
Despite her pain, Shan says she wanted to tell the world her aunt was more than just a number.
"I want her death to be a reminder we have severe problems in our society, in San Francisco," Shan said.
Shan says her aunt did not speak English and had no communication with Esparza.
