ABC7 News has learned that an adult male driver, as well as a female passenger were pronounced dead at the scene. Another female passenger was taken to a local hospital with life threatening injuries. An adult male passenger was also taken to a local hospital, but is expected to survive.
Alcohol and marijuana are suspected to be factors in the crash. Speed also likely played a role.
Casselino Drive is now back open to vehicular traffic after being closed for much of the morning while police conducted an investigation. Residents say this stretch of road has been a problem spot for years.
