Police: Phoenix serial killings suspect left behind shell casings

PHOENIX — The man arrested in a string of serial killings left behind bullet casings at each crime that authorities tested and linked him to the shootings, police said in documents released Friday that provide the most detailed narrative to date about a case that unnerved Phoenix neighborhoods last year.

The documents were released after media organizations including The Associated Press, Arizona Republic and Phoenix TV stations, went to court in a bid to get prosecutors to unseal the evidence that led to the arrest of 23-year-old Aaron Saucedo in nine killings.

Police say that in one of his killings, Saucedo opened fire on a man walking along a Phoenix street on New Year’s Day 2016 and then got out of his car and kicked him twice before calmly driving away. The documents also say video footage captured from a July 2016 shooting determined the shooter’s car was a BMW, the same model that Saucedo drove.

Saucedo emerged as a possible culprit just weeks after the last of the nine shootings. Two witnesses told authorities in August 2016 that Saucedo matched a composite sketch of the suspect and drove a BMW similar to one seen at the crimes. Homicide detectives interrogated him in December, about five months before he was arrested.

In the interview, Saucedo told authorities he drove a BMW and owned a 9 mm handgun, which he said had been stolen.

Saucedo told a judge last week “I’m innocent” in the hours after he was arrested. Dean Roskosz, one of Saucedo’s court-appointed attorneys, didn’t immediately return a call Friday seeking comment on the allegations made in the newly released document.

Police say Saucedo randomly opened fire on people after dark, primarily in a largely Latino neighborhood in Phoenix. Police say his victims include a 21-yearold man whose girlfriend was pregnant with their son and a 12-year-girl who was shot to death along with her mother and a friend of the woman. No motive has been established.
