Authorities are searching for a suspect in the deaths of a couple and their 5-year-old daughter in a Santa Barbara County home.

The bodies were found by detectives Thursday morning when they entered the home on Greenhill Way.

County sheriff's deputies sought a search warrant after they were asked to check on the family's welfare Wednesday evening and decided to open a suspicious death investigation.

The victims were 57-year-old Dr. Weidong "Henry" Han; his wife, 29-year-old Huijie "Jennie" Yu, and their daughter, Emily Han.

Sheriff's spokeswoman Kelly Hoover says the three were slain by an unknown killer. She won't discuss how they were slain or a possible motive.

Hahn owns the Santa Barbara Herb Clinic. The website says he practiced traditional Chinese medicine, including herbal treatments and acupuncture.
