Prosecutors say Eugene Roebuck was driving under the influence when he changed lanes and collided with a car on Highway 99 near McKinley Avenue.
Both cars went down an embankment.
20-year-old Mariano Cruz and his 18-year-old girlfriend, Emily Ochoa Ascencio, were both killed when their car hit a tree.
Roebuck has been out of custody, but the judge said he must pay a $150,000 bond by July 14th or he will need to turn himself into authorities.
