HAYWARD -- A Castro Valley woman found slain last week was shot twice and discovered in a bedroom closet by her teenage daughter, according to court documents released Wednesday.

Yun Yi Zhang, 45, was pronounced dead Friday inside her home in the 19000 block of Stanton Avenue after policed responded to her daughter's call to 911. Zhang's husband, 45-year-old Feng Mi, had disappeared after Zhang's body was discovered but surrendered to police on Monday.

Mi appeared before an Alameda County Superior Court judge Wednesday afternoon via video arraignment from a courtroom inside the Santa Rita Jail.

Mi, who speaks limited English and wore a red jail jumpsuit, did not speak during the hearing but rose from his seat when Judge Scott Patton said his name.

The judge told Mi he had been informed before the hearing that he needed a Mandarin interpreter and then postponed the hearing until Thursday. Thus far, Mi has not spoken with investigators about the case, police said.

Mi returned to his cell, where he was being held without bail on Wednesday.

According to a probable cause affidavit, Alameda County Sheriff's Office deputies were called about 4 p.m. Friday to the couple's home after their 14-year-old daughter dialed 911 to report she found her mother dead.

Deputies found Zhang in the master bedroom of the home, inside a closet, the affidavit states. Zhang had been shot twice and was pronounced dead at the scene.

After authorities identified her, investigators say they developed evidence which linked her husband to her death. They did not elaborate in court papers.

Investigators say the couple's 14-year-old daughter was not home at the time of the shooting. They also have an 8-year-old daughter, Alameda County Sheriff's Office Deputy April Luckett said, but it was not clear if the girl was home when the slaying happened.

Mi turned himself in to authorities late Monday at the Cal State East Bay Police Department in Hayward and was transported to the Alameda County Sheriff's Office Eden Township substation in San Leandro.

Police have not established a motive for the shooting. Sheriff's officials had deemed Mi armed and dangerous over the weekend after finding one of his two guns had been removed from the home.

The second firearm had not been located as of Wednesday, authorities said.

A silver 2013 Toyota RAV4 that Mi was driving was also recovered Monday near the Cal State East Bay campus, Luckett said.

The couple, investigators say, has a history of domestic violence. In 2009, authorities responded to the home three times for domestic-related disputes.

Anyone with information about the killing is asked to call the Sheriff's Office anonymous tip line at 510-667-3622.
