In February, CPS Energy sent out a warning to customers that would-be scammers were impersonating company employees.
Then on May 3, a man posing as a repairman at a local Walmart was charged with theft, accused of stealing $35,000 worth of copper pipes.
Following these events, the KSAT Defenders went in search of company logo shirts, purging the racks of both Goodwill stores and the Salvation Army.
There were many private company shirts, as well as both private and public school shirts found.
Salvation Army Operations Director Wanda Trayler said this was a real wake up call for her, as it is their policy not to sell any shirts with logos.
"Anything with names or company names we discard, and we try not to let anything pass through. We want to protect the community because we're part of the community," Trayler said.
Goodwill Industries shared their policy, which states they do not intentionally sell any garments, uniforms, or any other article of clothing related to law enforcement, the U.S. Military, or any city utilities.
Goodwill declined comment on other types of logoed shirts, including the dozen or so the Defenders found branded with company names.
While no city utility shirts were found, the Defenders were able to order some at a north side embroidery shop.
Big Star Embroidery owner Kathie Rowe, who refused to sell CPS Energy logo shirts, said it would be unethical and unlawful.
According to CPS Energy spokeswoman Christine Patmon it is also a safety issue.
"Company-wide, our policy is that our employees should discard their shirts responsibly, which includes cutting out the logo and discarding the shirts," Patmon said.
Another CPS safeguard is they never collect money at the door.
Patmon said if there is every any doubt about a CPS worker knocking on your door, you can ask for two forms of identification, as they are required to carry them.
You can also call their security hotline number for verification at 353-4000.
