Zamora, now 27, spends most of her days locked away in protective custody at a state prison for women, the Fort Worth Star-Telegram reported Wednesday.
Zamora was sentenced to life for the 1998 murder of Adrianne Jones near Fort Worth in a case that drew national attention. Her boyfriend, former Air Force Cadet David Graham, also received a life sentence in the case.
In the bid for a new trial, Zamora's attorneys accuse prosecutors of withholding key evidence that supports her claim that she did not help Graham kill Jones.
Prosecutors argued in the trials that Zamora was jealous and thought Graham had sex with Jones, who was beaten and then shot after being lured to a remote location.
Zamora is only allowed out of her cell for one hour per day for exercise. High-profile inmates are segregated sometimes because other prisoners are jealous, a prison official said.
Zamora will not be eligible for parole until September 2036, when she will be 58.
