The man believed to be responsible for the death of 44-year-old Cecilia Stanford appeared in court Friday.

22-year-old Dacota Deaver entered a plea of not guilty to manslaughter and criminally negligent homicide.

In October of 2017 police said Stanford was pushing her car after it broke down in Calallen and that is when an SUV slammed into her from behind. Stanford was taken to the hospital where she later passed away.

Deaver was arrested in January, three months after the incident, when an arrest warrant was issued.
