A Kansas City, Kan., man who died last weekend on Kansas Highway 10 in Johnson County had been traveling the wrong way on the divided highway for at least one mile before causing a head-on collision near Interstate 435, according to the Kansas Highway Patrol.

Capt. Dek Kruger said troopers suspect that Ezequiel Gallardo-Moncallo, 23, drove his 2001 Mazda 626 up the wrong ramp on the four-lane highway, and other motorists reported seeing him headed east in the westbound lanes just before the 1:43 a.m. Saturday crash with an Olathe man, who was headed the correct direction.

The Olathe driver, Brian J. Ingalls, 28, was taken to Overland Park Regional Medical Center, while Gallardo-Moncallo died at the scene. A condition update for Ingalls was not available Thursday evening. Kruger said troopers suspect alcohol was a factor in the crash, but they were waiting on lab test results, which could take months, before making a determination.

This is the third fatality crash since 2009 on Kansas Highway 10 in Johnson County in which one driver was headed the wrong direction for an extended period of time. Transportation and law enforcement officials classify wrong-way crashes differently than a cross-median crash in which a vehicle within seconds crosses the median and strikes another vehicle traveling the other direction.
