BUNNELL, Fla. -

A man accused of killing a clerk in a Flagler County gas station insists he wants to represent himself during his trial.

But a judge on Tuesday ordered a third mental evaluation before deciding on any motion pertaining to Joseph Bova II's legal representation.

The Daytona Beach News-Journal reports two experts have already examined Bova and reached differing opinions. His next hearing is scheduled for Sept. 2.Zuheily Rosado

Bova is accused of killing 32-year-old Zuheily Rosado in February 2013 as she worked alone in a Mobil Mart in Palm Coast.

Surveillance video helped link Bova to the killing. He was arrested almost seven months later in Boca Raton. His family hired a South Florida lawyer but Bova refused his services.

On Tuesday he reiterated his desire to represent himself.
