A judge held bail at $350,000 on Friday for a woman charged with DUI and gross vehicular manslaughter.
Prosecutors say Sunny Hall, 30, is responsible for killing two people on Interstate 8 in Alpine on June 12.
For unknown reasons, August’s car had rolled over on the freeway and Arevalo stopped his truck and got out to help her.
Soon after, Hall – suspected of driving under the influence -- approached the site of the rollover in the eastbound lanes of the highway. Her vehicle crashed into the two victims, killing them, CHP investigators said.
August was just days away from graduating from UCSD when she died. Arevalo was a beloved and well-respected veteran teacher.
Hall pleaded not guilty to the charges. If convicted, she faces up to 14 years in prison.
On Friday night, August’s mother, Dawn, spoke to NBC 7 for the first time since charges were filed against Hall.
Though time has passed, the pain of losing her daughter has not.
“It's still hard. It's still hard to look at the person who has done so much destruction to two families,” said Dawn. ”There has to be consequences for her actions and I think a prison term would be in order.”
Hall is scheduled to appear in court again on December 14 for a readiness hearing.
