A photography business has been set up in South Florida under Casey Anthony's name, and an address listed for the business belongs to a private investigator with ties to the mother acquitted of killing her 2-year-old daughter.

Documents filed with the Florida Division of Corporations show that Case Photography, LLC was established last November.

An address listed for the business is the West Palm Beach home of Patrick McKenna, a private investigator with ties to Anthony.

McKenna refused to talk to a reporter outside his home on Monday.

Messages left on a voicemail and email address listed on the documents weren't returned.

Anthony was acquitted in 2011 of murdering her 2-year-old daughter, Caylee. Her trial was broadcast live on cable television and garnered worldwide attention.
