A laptop computer containing proprietary software that the owner says is worth $500,000 was part of the take in a residential burglary of a home on Alamos Road in Portola Valley, deputies from the San Mateo County Sheriff's Office said.
The Nov. 15 report noted the theft of the laptop and software -- software that was coded by the resident -- along with a Glock 9 mm semiautomatic handgun with an estimated value of $1,200, ammunition, and a $1,500 Nikon camera, deputies said.
The thief or thieves entered through an unlocked bathroom window next to the master bedroom and left by the rear door, which they left unlocked, deputies said. The theft could have had higher losses; there were "multiple items of value" not taken, deputies said.
Investigators say they have no witnesses and no suspects, deputies said.
