Homicide detectives announced a $30,000 reward for information on the unsolved murders of a husband and wife, who were murdered in their home in Diamond Bar last October.
Cheng Long Weng, known as David, 60, and his wife Mei Chu Chung, known as Marian, 57, were stabbed to death during a home invasion robbery, the Los Angeles County Sheriff's Department said Wednesday.
"My parents were educators, they touched the lives of many children and their parents by creating something beautiful," said the couple's son, Dr. Gary Wang.
"They were taken away from my life so suddenly and so brutally by burglars," he said.
Their bodies were found inside their home in the 3300 block of Bent Twig Lane on October 20, and more than $10,000 in cash was stolen.
"At this point we believe that the motive for this crime is robbery," said Homicide Bureau Capt. Steve Katz.
"This is extremely unusual, and there is no link to any other type of activity related to this particular incident, it appears to be isolated and tragic," Katz told reporters.
The intruders may have suspected the couple kept a large amount of cash in their home.
Anyone with information was asked to call homicide detectives at (323) 890-5500.
