(AP) — Jodi Arias heads back to court as jurors consider whether the death penalty should be an option for sentencing the former waitress after convicting her of first-degree murder last week.

The 32-year-old aspiring photographer admitted killing her onetime boyfriend Travis Alexander in June 2008, at his suburban Phoenix home. She initially denied involvement then later blamed masked intruders. Two years after her arrest, she said it was self-defense when he attacked her after a day of sex.

Prosecutors said she planned the killing in a jealous rage as Alexander wanted to end their affair.

Testimony began in early January. The jury reached its verdict last Wednesday after about 15 hours of deliberations over four days.

Jurors on Wednesday will hear testimony before deciding whether the death penalty should be an option for sentencing Arias.
