Upon arrival, officers found the vehicle inside of a business lobby and two individuals outside of the vehicle.

Officers and medical personnel provided emergency medical aid to the individuals at the scene.

A male passenger identified as Jeffrey Kassir, 23, who is believed to have been the driver, was pronounced dead at the scene, police said. A female passenger identified as Amanda Mosqueira, 22, was transported to the Flagstaff Medical Center where she was pronounced dead. Investigators are working to notify next of kin and will provide additional information as it becomes available.

The investigation is ongoing and factors, such as speed, have not yet been determined. Members of the Criminal Investigations Unit as well as the Collisions Reconstruction Team were called as a part of the investigation.

The damaged business lobby belonged to the local employment agency OnCall Staffing, which was confirmed by the vice president of the business, George Sideris. The agency is located in the Continental Plaza at 5200 E. Cortland Blvd. and is temporarily relocating to the A-19 unit beginning Monday. OnCall staffing will resume regular business hours from 6 a.m to 5 p.m. at the temporary location on Tuesday.
