The State Appellate Court on Tuesday upheld the conviction and three-year prison sentence of a Kent woman who violated her probation after serving time for a 2004 drunken-driving crash that killed one of her friends.

Alia Altajir, 24, is the granddaughter of Mahid al-Tajir, a United Arab Emirates billionaire with a net worth of $4.3 billion, according to Forbes magazine.

Images on Ms. Altajir's Facebook page showing her using alcohol were used by State's Attorney David Shepack to support the violation of probation charge, which was handed down in 2009.

Mr. Shepack argued a pattern of behavior continued after Ms. Altajir avoided a five-year prison term for the death of 18-year-old Dustin Church, according to appellate court documents.

Ms. Altajir was arrested on April 17, 2009, in Greenwich after a car she was driving hit two parked cars. She had failed to use an ignition interlock breath device and was driving with a suspended license, police said.

Interlock devices don't allow a person to drive if he or she is drunk. One has to breathe into a tube and pass the breath test before the car starts.

Ms. Altajir lived with her mother, Khalid M. Altajir, in Kent at the time of her 2009 arrest.
