Alameda County Sheriff's deputies want to talk to 46-year-old Feng Mi, who hasn't been seen since early Friday. He's considered a person of interest in the shooting death of his wife, 46-year-old Yun Yi Zhang. She was found dead of a gunshot wound Friday afternoon inside the couples Castro Valley home.
The couple's two daughters, ages 14 and 8, are safe in protective custody.
"We're not calling him a suspect yet we have not been able to speak with him," said Alameda County Sheriff's spokesperson Dept. April Luckett. "We don't know if he was home yesterday. However, all the information that we found, all the evidence at the house does point to him and it being suspicious."
Neighbors report hearing gunshots about 1 p.m. on Friday. Two hours later, sheriff's deputies arrived at the house after the couple's teenage daughter discovered her mother's body when she got home from school.
"I said to myself that sounds like a gun," neighbor Emile Lassalle said. "I didn't pay attention to it. One bang, just one."
"I'm in shock, it's crazy," said Cynthia Yotsenya.
Yotsenya was renting a downstairs apartment from the couple. Police say there's been a history of domestic violence at the home, but she says she never heard or saw anything in usual..
"He set up my cable," Yotsenya said. "Whenever I had an issue back there I'd shoot him an email and he'd take care of it."
Mark Sand coached both the couple's daughters on the local swim team.
"They were both around the pool a lot," he said. "And they'd bring their kids there and yeah, good supportive parents. Not super energetic or outgoing, but their presence was there."
Police say Feng Mi may be driving the family's 2013 silver Toyota RAV4, with dealer plates from Dublin Toyota. He's considered armed and dangerous.
