PHOENIX — Authorities say an 18-year-old Mexican citizen who told police he’s in the United States illegally is accused of fleeing from police following a purse-snatching and causing an auto wreck that killed a pedestrian.

Phoenix police say Brian Israel Morales-Diaz was driving a car that collided with an SUV after running a red light, causing the SUV to strike the pedestrian Thursday.

According to police, the car reportedly was stolen and had sped away from a park where a woman’s purse was snatched. A police officer sent to the park was chasing the car when the crash occured.

Morales-Diaz remains jailed on suspicion of first-degree murder and other crimes after making an initial court appearance Sunday. Court records don’t list a defense attorney who could comment on the allegations.
