The Douglas County Sheriff's Office is investigating eight burglaries from unlocked vehicles in Genoa that occurred June 29-30.
Sheriff's spokesman Sgt. Jim Halsey said the burglaries occurred on Pioneer Trail, Kinsey Way, Reese Court, Genoa Highlands and Cloudburst Canyon.
Halsey said there were no suspects.
Stolen items included weapons, money, wallets, compact discs, sunglasses and electronic items including global positioning systems, iPods and cell phones.
The weapons included two firearms, a shotgun and a handgun. Halsey said the handgun was stolen from a vehicle.
The shotgun was stolen from the garage after the suspects discovered the victim had left his keys in the vehicle.
The suspect used the keys to unlock the side door to gain entry.
Secret Witness is offering a $500 reward. Anyone with information is asked to call investigations at 782-9905 or Secret Witness at 782-7463.
Halsey urged residents to record valuable electronic items.
The description and serial number are the only means to identify items if they are recovered after being stolen.
"If any of your valuable electronic items do not have a serial number, or have only a sticker containing the serial number, we suggest inscribing/engraving it with an identifying number," Halsey said. "Don't use your date of birth or Social Security number as it may lead to identity theft."
If your vehicle has been broken into, do not touch or adjust anything in it, on it, or around it, Halsey said. Call the Douglas County Sheriff's Office to report the incident.
Report suspicious activity to the Douglas County Sheriff's Office at 782-5126, he said.
