An official with the Pierce County Medical Examiner's office confirmed to ABC 4 News that Astrid Valdivia died from "multiple gunshot wounds" after an encounter between Kitsap County deputies and Anthony Allen Martinez on Sunday.
The shooting took place in Port Orchard, Washington after police said Martinez fired a handgun at officers during a foot pursuit outside a Walmart store.
According to police, witnesses reported seeing a suspicious man with a gun at the Walmart and when officers from the Kitsap County Sheriff's Office responded, Martinez ran and fired shots, hitting and injuring two officers. A third officer pursued and returned fire, killing Martinez.
Police say Astrid Valdivia was with Martinez as a companion ran to his aid. She was also shot, and police say she died after being taken to a local hospital.
Martinez was a suspect in a child kidnapping case out of Clearfield in October in which police say he took Valdivia from North Davis Junior High School and traveled with her to California, where he was later arrested.
Valdivia was taken back to Utah, and was living in South Salt Lake foster home when she disappeared on Tuesday, January 18. Police say she removed a tracking monitor she was wearing.
South Salt Lake Police reported her missing, and suspected that she was in the illegal custody of Martinez.
On Friday, medical examiners were able to positively identify Valdivia using by matching her dental records.
