Few details were immediately provided about the double stabbing, which occurred in the 3300 block of Bent Twig Lane around 9:45 a.m., a sheriff's news release stated. Homicide detectives were investigating.

The block is residential and lined with large, single-family homes.

A friend of the pair went to their home to check on them and found the bodies, authorities said.

There were signs of struggle, but the home did not appear to be ransacked, investigators on scene said. They would not say where in the home the couple's bodies were found.

The victims died at the scene, according to the department. Their names and ages have not yet been released.

A neighbor said the couple, originally from Taiwan, had lived at the home for many years. Previously, the neighbor had told KTLA the two were from China.

"I can't imagine who would do this to them," Kevin Lu said. "I'm really very, very sad about it."

Lu said the couple ran an art school out of their home that his son attended.

Police believe the stabbing occurred between Wednesday night and Thursday morning, because someone spoke with the couple Wednesday evening.

Anyone with info about the stabbing has been asked to call the Sheriff's Department's Homicide Bureau at 323-890-5500. Those who wish to remain anonymous should leave a tip through Crime Stoppers by dialing 800-222-8477, or by visiting the website
