WEST PALM BEACH, Fla. (AP) — State records show that Casey Anthony has filed documents to start a private investigation firm in South Florida.

Anthony, who was acquitted of killing her 2-year-old daughter, Caylee, nine years ago, filed the paperwork with the Florida Division of Corporations in mid-December.

The limited liability company, Case Research & Consulting Services, has an effective date of Jan. 1, according to state records.

The address listed for the company belongs to Patrick McKenna, according to Palm Beach County property records.

McKenna was the lead investigator on Anthony’s defense team during her 2011 trial.

Anthony was acquitted of her daughter’s murder and child abuse and manslaughter charges.
