The thieves stole belongings that the victim says are worth half a million dollars. The theft happened this week in the Benedict Canyon area in the middle of the day while the victims were gone.
Video shows the crooks leaving with bags of stolen goods. Stolen items include a wedding ring - a family heirloom - that the victim gave to his wife.
The victim says the intruders managed to get inside his home without tripping the alarm. He says his neighborhood provides security patrols, but the burglars pulled up in a Porsche and ransacked his home.
Donna Perris lives across the street and says she saw the unassuming Porsche when she was out with her dogs.
Perris says neighbors actively watch out for each other. Neighbors say they are now considering what other safety measures they can use to protect themselves and each other.
The victim lives in a neighborhood in the LAPD's West Los Angeles Division, where burglaries are down 10% since early August, according to the agency's crime statistics
LAPD says the burglary is under investigation.
