BEXAR COUNTY, Texas - More than two years after a wrong-way crash claimed the life of 26-year-old Yulissa Valero, the man accused of causing the collision is now on trial in Bexar County.

Testimony began Tuesday in the murder trial of Christopher Navarro, who prosecutors allege was driving the wrong way on Interstate 35 in January 2024 when he crashed head-on into the vehicle Valero was riding in.

For Valero's family, the start of Navarro's trial marks the latest step in a long and emotional journey through the criminal justice system.
