Trooper Joseph Ynostroza was killed in an automobile crash on U.S. Route 160 near Alamosa while en route to Cortez from Denver.
During the drive, his patrol car veered into oncoming traffic and was struck head-on by a tractor-trailer. Although he was wearing his seat belt and his airbag deployed, the force of the impact was so severe it caused fatal injuries.
Trooper Ynostroza had served with the Colorado State Patrol for 16 years. He was survived by his wife and three children. His son later went on to serve in the same agency.

Where do I begin? The family has told me stories about you throughout my entire life, and I am so sad that I will never be able to experience your jokes or your love in person. I have so much admiration for you and the man that you were. You raised a great family that went on to do great things and you would be so proud. Darian now has two beautiful baby boys of his own, Noah and Kai. They love fishing and camping just like you did, you guys would’ve had so much fun together. Please keep watching down on us from heaven. You are missed and loved a lot by many, rest paradise.
