Jewelry Store Robberies Soaring In California December 13, 2021 (0 comments)


New York, NY—Jewelry store robberies have markedly increased recently, including a dozen smash-and-grab robberies in California, says the Jewelers Security Alliance. The five most recent smash-and-grab robberies in California occurred on November 27 in Chino Hills, on December 2 in San Jose and Rancho Dominguez, on December 3 in Sacramento, and on December 7 in Carmel By The Sea.

In Chino Hills, four suspects sprayed a chemical substance at a jewelry store employee and demanded the employee go to the back of the store. The suspects used tools to smashed several showcases and fled in a waiting vehicle. The incident occurred Nov. 27 at 3:23 p.m.

In Rancho Dominguez, on December 2 at 11:30 a.m., several suspects were shopping in a jewelry mall and faked a fight to distract the security guards. They smashed showcases and took jewelry items, and two employees were shoved to the ground.

The robbers had multiple cars waiting with engines running. Police were able to take two suspects into custody and are looking for five more, says JSA.

The same day, in San Jose, four masked suspects pictured above used hammers to shatter showcases at a retail jewelry store.

On December 3 in Sacramento, the two white male suspects pictured below entered a retail jewelry store and looked around for a minute. The suspects both pulled guns on the husband and wife owners, and backed them into a corner before cleaning out the jewelry cases. The victims report that one of the suspects was in the store earlier in the day and then returned to rob them.

Finally, in the Dec. 7 incident in Carmel By The Sea, three people got out of a car with sledgehammers and entered a retail jewelry store. They smashed showcases and took merchandise, but when they saw a security guard they fled. The California Highway Patrol was later able stop the car, and two suspects were detained, while the other two were not located.

In this dangerous time, JSA reminds jewelers of its recommendations regarding smash and grab robberies:

1. Do not resist in a smash and grab robbery. In addition to sledgehammers and other dangerous tools, the suspect(s) may be armed with guns.  

2. Showcases with burglary-resistant, laminated glass on the front and sides, and special frames, can withstand many blows with a hammer and can prevent or reduce large losses.JSA has not seen robbers take retaliatory action when laminated glass is used and robbers are unable to enter a showcase or are able to take only a small amount of merchandise from a small hole. Furthermore, robbers frequently cut themselves on small holes and leave behind valuable DNA evidence from blood.

3. Having an audible glass breakage alarm on your showcases can scare smash and grab robbers away, who are trying to remain in a target store for less than a minute.

4. Having buzzers on the door can help to keep out potential robbers.

5. Hiring armed, off-duty police officers in the store is a deterrent to smash and grab robbers.

6. Spreading high end watch and loose diamond merchandise among several showcases, and not concentrated in one showcase, can reduce the amount of the loss in a smash and grab robbery.

7. Surveillance photos from eye-level cameras inside and outside the store provide excellent evidence for police. Ceiling cameras too often capture useless photos of the top of heads or hats.

8. Keeping a log book of suspicious incidents, and putting aside and saving surveillance video of suspicious incidents, can be a great help in subsequent investigations.

9. Sharing information and photos among local jewelers and police, and with JSA, regarding casings and suspects can help prevent crime and assist with investigations.

JSA asks anyone who has information on those cases or the suspects involved, or any jeweler that has a crime or even a suspicious incident at their store, to please contact JSA at (212) 687-0328 or
