A man was killed in multi-vehicle crash Sunday after experiencing a medical emergency on the Eisenhower Expressway on the West Side.
Byron McClain was westbound about 1:35 p.m. on Interstate 290 when he suffered an “unknown medical emergency” that caused him to veer out of his lane and crash into a concrete barrier, Illinois State Police said.
McClain, 47, then veered into oncoming traffic and struck two vehicles, state police said.
He then struck a light pole before swerving back into the westbound lanes and hitting a third vehicle, according to state police.
