A court record released Friday offers a glimpse into the sprawling case against Aaron Saucedo, the 24-year-old Phoenix man police accuse of killing nine people between 2015 and 2016. 

Phoenix police say Saucedo is the lone “Serial Street Shooter,” a man who hunted his victims in predominantly Hispanic neighborhoods at night and seemingly at random. Saucedo has said he is innocent.

The case spanned 11 months, various Phoenix neighborhoods and 12 separate shootings. But the linchpin of the detectives’ case against Saucedo rests on the guns he owned at the time of the crimes, when he bought them and where their bullets ended up.

Though tips from the community initially pointed police in Saucedo’s direction, a newly released probable-cause document spends the bulk of its space describing the suspect’s rotating collection of firearms.

Saucedo has only been charged in one of the 12 suspected incidents, the August 2015 murder of his mother’s boyfriend, Raul Romero. The other victims seemed to be picked at random, and police to date have not offered a motive.

Saucedo was initially arrested in Romero’s murder in April. Police publicly tied him to the 11 other incidents on May 8, but offered scant details on the investigation until Friday.

Here is the most compelling evidence police say they have on Saucedo: 

Cars

Police said last year that the street shooter would likely be a man with access to several cars. Saucedo was known to drive both a gray Hyundai Sonata and black BMW — two vehicles reported by witnesses at some of the crimes. 

Bullet casings

Police executed search warrants on the BMW and Sonata, the latter of which had been sold. Fourteen bullet casings were discovered in the Sonata, as well as one in the BMW.

All but one of the casings in the Sonata was fired by a 9mm handgun. Police say that same 9mm handgun was used in nine of the street shooter crimes. 

A .380 casing found in the Sonata has been linked to the gun that police say was used to commit one of the first murders in the series.

Guns and pawn shops

Police are tying Saucedo to three different guns and say evidence places them in his possession at the time of all the street shooter crimes. 

Pawn-shop records show he purchased a High-Point 9mm gun on July 2, 2015, and sold the same one on Sept. 1, 2015. In the interim, police say that exact weapon fired the casings found at a residence on Aug. 12, 2015, and in the murder of Raul Romero on Aug. 16, 2015.

On the same day he sold the High-Point 9mm, police say, Saucedo purchased the Bryco Arms .380. That gun, according to ballistics tests, was the weapon used to kill Jesse Olivas on Jan. 1, 2016, police say.

Police said Saucedo purchased another 9mm handgun on Feb. 21, 2016, which would have fit the timing of nine other incidents between March and July 2016. It is unclear from the report whether detectives are in possession of this weapon.
