Huijie Jennie Yu, 29, was one of three members of a Goleta family found dead in their Greenhill Way home on March 23, 2016. The other victims were her husband, Dr. Weidong Henry Han, and their five-year-old daughter, Emily Han. Sheriff’s deputies discovered the scene during a welfare check and investigators determined the killings were not random.

Authorities arrested 27-year-old business associate Pierre Haobsh in San Diego County; police say they recovered a loaded handgun and property belonging to one of the victims in his possession. Investigators described a financial motive connected to a business relationship with Dr. Han and characterized the killings as planned. Haobsh faces multiple murder charges with enhancements accusing him of killing for financial gain, committing multiple murders, and discharging a firearm causing great bodily injury.

What information about the victims’ lives or the business dealings leading up to March 23, 2016, might help explain how this unfolded?
