Aaron Saucedo.

The man accused of being the "Serial Street Shooter" is scheduled for arraignment this morning in Maricopa County Superior Court.

Aaron Saucedo faces a total of nine counts of first-degree murder, plus a host of other felonies.

Phoenix police arrested the 23-year-old in April on suspicion of a 2015 homicide.

Less than a month later, investigators identified him as the "Serial Street Shooter" who police say killed eight people in 2016.
