Javier Ambriz Garcia, 54, was riding westbound on Interstate 70 in Kansas City, Kansas, in the early morning hours of December 24, 2016, when gunfire struck the SUV he occupied. The driver, 59-year-old Socorro Olivas, and Ambriz were mortally wounded; the vehicle then crashed into a bridge and stopped in the roadway. A westbound car shortly afterward collided with the immobilized SUV.

Authorities say shots were fired from another vehicle into Olivas’ SUV as it traveled on the interstate, and investigators found no signs of a roadside altercation or carjacking. Officials publicly identified the victims and appealed for drivers who might have seen muzzle flashes, erratic driving, or a fleeing vehicle around 3 a.m. Detectives later reported no credible leads, no suspect description, no vehicle tag, and no apparent motive. No arrests or named suspects have been announced. A brief obituary recorded Ambriz’s name, age, and date of death.

If anyone drove that stretch of I-70 around 3 a.m. on Christmas Eve 2016 and saw anything — however small — please come forward.
