In a federal criminal complaint filed on August 24th in the United States District Court in Wichita, 21-year-old Azucena Garcia-Ferniza was charged with one count of possession of a firearm by an illegal alien in the United States.

The handgun is believed to the murder weapon used in the May 6th shooting death of Salina teenager Allie Saum. According to an arrest affidavit, Garcia-Ferniza was in possession of the weapon at the time of her arrest on May 7th. She was charged with felony obstruction by Saline County authorities for her involvement in the canse

Garcia-Ferniza was taken into custody by federal authorities at the Holiday Inn Express, 755 W. Diamond Drive, on Wednesday afternoon.

Allie Saum was shot on the evening of May 6th in what prosecutors have called a case of mistaken identity. Police say the shooting was the result of a fight that occurred earlier that same day. The suspects were part of a group of people that were out seeking revenge for the fight. One of the suspects mistakenly identified the male driver of a pickup, later identified as Saum’s boyfriend, as someone that had been involved in the fight. Shots were fired into the pickup in the 800 block of Russell and Saum, who was in the passenger’s side of the truck, was struck in the head.

She died shortly after midnight on May 7th.
