AURORA, Colo. (CBS4) – Emergency crews took a mother and an infant and another driver to the hospital after an overnight crash that closed Parker Road.

Police say the crash happened at about 2 a.m. Monday on South Parker Road near East Lehigh Avenue when a Jeep slammed into the back of a Dodge Caliber and both cars rolled over.

The mom, Shalimar McComas, 35, of Aurora, is expected to be okay but the infant, a 6-week-old girl named Lizbeth, may have suffered head trauma. They were both in the Dodge, which rolled over into a ravine.

“We always do our best to protect the innocent. The most innocent of innocents is the young ones. It broke my heart when I got the phone call from lieutenant,” Aurora police spokesman Lt. Chuck DeShazer said. “No family needs to endure this, especially around the holidays.”

The driver of the Jeep, William Page III, 21, of Denver, also sustained serious injuries and was in the hospital in intensive care.

A witness told CBS4 the Jeep passed her right before the crash at Quincy doing about 100 mph.

“She was doing 55. She says the Jeep was at 100 when it passed her,” DeShazer said.

All of the northbound lanes and three southbound lanes of Parker Road were closed for the entire Monday morning commute from Quincy to Hampden.

DeShazer said McComas had just dropped her husband off at work in Parker and was returning home when the collision happened.

Aurora police said Lizbeth McComas was in intensive care but late Monday her condition was upgraded. On Tuesday her family said she has been eating and has had no seizures.

Page is also hospitalized and has been given a felony blood draw where he is tested three times over a period of time to determine if he was drinking or doing drugs. Because Page has experienced so much blood loss and has been given replacement blood, it could affect the results of the test.

Anyone who might have more details about the crash is asked to call Detective Steve Chinn at (303) 739-6342.
