As proof that the Grinch is not just some imaginary Dr. Seuss character, see Exhibit A: Sandra Lizbeth Contreras-Velazquez.

Just a week before Christmas, San Jose police announced that in the lead-up to the holiday season, Contreras-Velazquez was allegedly stealing the jewelry of others. But not just anyone with a gold chain. Contreras-Velazquez is suspected of tricking children into giving away their jewelry so she could sell it for profit.

In some cases, according to the Mercury News, she asked to see the kids’ jewelry before giving back counterfeit necklaces or costume jewelry. Sometimes she just removed the jewelry and went on her way.

If that wasn’t bad enough, Contreras-Velazquez allegedly used a toddler as a prop to blend in with other parents and prey upon unsuspecting children outside of six San Jose elementary schools: Kennedy, Washington, Russo/McEntee, Grant, Trace and Horace Mann.

Booked at the county jail on six counts of felony grand theft and one count of misdemeanor possession of drug paraphernalia, Contreras-Velazquez was being held on $100,000 bail Saturday.

Assuming she gets out in the coming days, Contreras-Velazquez might just be in line for a lump of coal. Thankfully, she can squeeze all she wants but a diamond isn’t likely to be header her way.
