A 50-year-old Newark woman pled guilty to stealing from her own mother's investment accounts for a year and a half, beginning in the summer of 2017, the Delaware Department of Justice announced Friday. 

According to the DOJ, Karen Warrington admitted to impersonating her mother in June 2017 to steal money.

She was caught thanks to a 2018 amendment to the Delaware Securities Act, which protects vulnerable populations, officials said. Warrington's plea is the first to result from a Report of Suspected Exploitation of a Senior or Vulnerable Adult submitted by to the Department of Justice Investor Protection Unit. 

Warrington pled guilty to theft of $50,000 or more and identity theft. She'll be sentenced in March 2020.
