The pool of prospective jurors at the sentencing trial of convicted killer Samuel Dieteman is down to 40 people.
Lawyers are scheduled to return to court on June 25 to complete jury selection.
Dieteman faces a possible death penalty after pleading guilty to two murders in metro Phoenix's Serial Shooter attacks.
Opening arguments are expected to begin within one to three weeks after jury selection is completed.
Earlier this year, the 33-year-old testified against his former roommate, 36-year-old Dale Hausner.
Dieteman told jurors that he and Hausner cruised streets looking for strangers to shoot.
Hausner was given six death sentences and hundreds of years in prison for killing six people and attacking 19 others in 2005 and 2006.
