Chicago
Police Officer Killed in Tragic Accident

CHICAGO (EmergencyNet
News) - A Chicago Police Department squad car plunged 25 feet Monday
from an overpass onto the Dan Ryan Expressway on the city's South
Side. A Chicago police officer was killed and a second officer was
critically injured early Monday when their car swerved, vaulted
a curb and crashed through the guardrail on 79th Street.
Police said
the car had swerved to avoid pedestrians during an emergency call
shortly after midnight. Killed was 6th District Patrol Officer David
C. Evans, 39, an 11-year veteran and a father of three. He had recently
switched from days to the night shift to spend more time with his
children.
The driver
of the car, Patrol Officer Estella Johnson, 33, was in critical
condition at Christ Hospital in suburban Oak Lawn with broken ribs
and other injuries.
The 25-foot
section of railing where the accident occurred, built of three-
tiered beams of aluminum, appeared much newer than an adjacent stretch
of rusty railing on the eastern part of the south side of the overpass.
But the concrete holding the guardrail appeared crumbled in places,
and the force of the car ripped the support poles from their bases.
Current construction practice uses steel for such guardrails, or
concrete barriers.
Experts say
that they doubted that having a concrete barrier would have made
a difference. A spokesman for the city Transportation Department
said, "That guardrail can only hold against so much. We had no indication
there was a problem before the accident occurred."
Police said
the two officers, who were paired for the first time on Sunday night,
were eastbound on 79th with their lights and siren activated. They
were responding to a call for help from paramedics in the 7900 block
of South Vernon. The police car swerved to avoid striking a pedestrian
in the road, then swerved again to avoid striking other pedestrians
at a bus stop. The car crashed through the guardrail and cyclone
fence, flipped upside down and landed in the northbound lanes of
the Dan Ryan Expressway.
Accident investigators
said that the car had been traveling at a high rate of speed. But
because the car hit a concrete curb and guardrail, it will be difficult
to determine its speed, according to police.
