|Recently, traveling criminals have been presenting themselves as employees of the water company testing resident’s water. |
Once inside of the residence they either distract the homeowner while another subject rifles through the home looking for valuables, or they "accidentally" spill or spray a liquid on the victim’s hands and tell them to remove their jewelry because the liquid is an acid. Once the jewelry is removed, the subjects distract the victim and take the jewelry.
To protect yourself, don't open the door for strangers and report suspicious people to the Sheriff.
