Crime in CA: Two Smash & Grabs and JSA Recommendations January 12, 2022 (0 comments)


Upland, CA and Rancho Cucamonga, CA--Two grab and run crimes were recently reported in California.

Upland, CA--Four smash and grab robbery suspects have been arrested who were involved in an attempted robbery at a retail jewelry store. Two were on parole, and one was on probation and had an outstanding federal probation warrant.

Rancho Cucamonga, CA--Smash and grab robbers attacked a retail jewelry store and currently remain at large.


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. It can be prudent when smash and grab robbers are particularly active not to display an entire inventory of highly targeted product, such as heavy gold chains, but rather keep some quantity in the safe.

8. 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.

9. 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.

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