CHICAGO (CBS) — A 25-year-old single mother was killed Tuesday morning in a high-speed crash in west suburban Berwyn.

Berwyn Police Chief Michael Cimaglia said a Nissan was speeding east on Ogden Avenue near Ridgeland Avenue shortly before 3 a.m., when the driver crossed the center line, and slammed head-on into a Pontiac heading west.

The driver of the other car, 25-year-old Mayra Rivera of Plainfield, was pronounced dead at the scene. Cimaglia said she leaves behind a 6-year-old son.

Investigators were waiting for fingerprint evidence to confirm the identity of the driver of the Nissan. Police also were waiting for a warrant to draw his blood for a sobriety test.
