SAN DIEGO - The three-mile stretch of Interstate 8 in the Alpine area shut down as part of an investigation into a fatal crash earlier this summer reopened early Tuesday.

According to the California Highway Patrol, eastbound lanes of I-8 closed between Dunbar Lane/Harbison Canyon Road and Tavern Road at 11 p.m. Monday until 4 a.m. Tuesday.

Drivers on eastbound I-8 were detoured onto Old Highway 80/Alpine Boulevard at Dunbar Lane/Harbison Canyon Road, and then back onto I-8.

On June 11, UC San Diego student Angela August and Jimmy Arevalo were struck and killed on the roadway, allegedly by a car driven by 30-year-old Sunny Hall.

The CHP will test the lighting conditions to see how far a driver can see at night and provide that information for the San Diego County District Attorney's Office.

Hall was arrested the night of the crash on suspicion of DUI but was released after three days with no official charges.

"There are some circumstances that the DA has to make sure are all in place and are fully investigated before charges are presented," said CHP Officer Brian Pennings.

10News went to Hall's home in El Cajon and was told she was not there. 10News was told that she left the state. However, officers said they may have new information that could change that.
