Ann Margret Mason, 39, of New Smyrna Beach, Florida, has been missing since August 19, 2003. She was last seen after being released from jail on September 19, 2003, but her disappearance was not reported until August 19, 2009, when her sister filed a missing persons report. That six-year gap in reporting has left major holes in the timeline and the circumstances of her disappearance.

Mason was on probation for felony grand theft at the time and was classified as an absconder. She may have used several aliases, including Lassone, Priester, and Tassone. She is described as a Caucasian woman with blonde hair, blue eyes, and about 5 feet tall. The New Smyrna Beach Police Department continues to investigate, but few leads have emerged and the case is cold.

Did anyone who knew Ann or recognize the aliases Lassone, Priester, or Tassone have contact with her around 2003–2009?
