A Webster plumbing and heating contractor has been found guilty on larceny charges for work performed in the Worcester County area, Attorney General Martha Coakley announced today. 

Daniel Watterson, 43, was found guilty on Wednesday by Judge Richard Tucker in Worcester Superior Court on charges of larceny over $250 of a victim over sixty years of age and larceny over $250 by false pretenses. Sentencing will be held at a later date. Additional charges are pending.

"The defendant exploited his position as licensed plumber and oil burner technician to steal from vulnerable consumers by fraudulently billing them and charging them without their consent, leaving them with an undue financial burden," Coakley said in a statement. 

Watterson, a plumbing and heating contractor operated in the Worcester County area under the business names "The Clog Specialist," "Dan the Clog Man," "Dan the Heating Man," and "DW Plumbing & Heating."

According to authorities, Watterson would overcharge customers, sometimes claiming the bill was a flat rate for the job, and also charged a customer’s credit card without consent.
