SDPD Identifies Victims, Suspect in Torrey Highlands Double-Murder Suicide

A couple found dead in their Torrey Highlands home over the weekend and their son who was suspected in their deaths before taking his own life were identified by police Wednesday.

Yi Cheng, 58, and his wife, Xiaoqun Fang, 58, were found dead inside their Torrey Highlands home on Saturday, August 17. San Diego police believe they were killed by their son, 30-year-old Fang Cheng.

Fang Cheng, a 2007 graduate of Westview High School, had jumped off an overpass to his death along Interstate 805 the night before his parents were found, police said. 

San Diego Police Department Lt. Martha Sainz confirmed Monday that Fang Cheng had jumped from the Eastgate Mall overpass on I-805 just before 2 a.m. Friday. 

On Saturday, the couple was supposed to catch a flight to San Francisco but when they failed to arrive, concerned family members asked San Diego police officers to make a welfare check at the couple's home.

Officers got no answer to knocks at the door and calls to the home on Via Rivera.

Sainz said officers then looked through a rear window and saw a person lying on the floor. Officers forced their way inside the home and discovered the couple dead inside with trauma to their upper bodies.

Sources within SDPD told NBC 7 the husband and wife were both stabbed multiple times.

No one other than the victims was found inside the home, police said, and the contents of the home did not appear to be disturbed.

Police are trying to determine a motive for the killings.

On Monday, Yi Cheng was identified by his supervisor as a Qualcomm employee.

"His personality was very quiet. Always tried to get the best job done at work," said Murali Bharadwaj. "Always a very pleasing, very personable character."

Co-workers of Xiaoqun Fang told NBC 7 she had recently retired from Scripps Research Institute.

Torrey Highlands is a residential area south of State Route 56 and west of Black Mountain Road and Interstate 15.
