PHOENIX -- Ticket scalping is nothing new in the sports and music world, but for a murder trial?Dozens of people flock to court each day for a chance to score one of a handful of seats open to the public in Jodi Arias' ongoing murder trial in Arizona. The seats are provided on a first-come, first-served basis, and nearly four months into the trial, the crowds are growing.This week, one trial regular sold her spot to another person for $200 -- and both got reprimands from the court Tuesday.Desiree Lee, a regular attendee, said another woman had traveled from Michigan to see the trial but couldn't get a seat because she was too far back in line."She was asking a couple of people ahead of me if they wanted to sell their seats," Lee, who lives in the area, told ABC15 in Phoenix. "I said yes because I can come every day if I wanted to ... I seriously didn't know I was going to get in trouble."I'm a little embarrassed more than anything," Lee added.She said she was told to return the money. The purchaser kept her seat for free.Court officials confirmed the incident.Arias faces a potential death sentence if convicted of first-degree murder in the June 2008 killing of her one-time boyfriend at his suburban Phoenix home. Authorities say she planned the attack on Travis Alexander in a jealous rage.Arias initially denied involvement then later blamed it on masked intruders.Two years after her arrest, she said it was self-defense.The trial continued Wednesday afternoon as the prosecution called witnesses ahead of closing arguments next week.
