An investigation continues into a March 28 wreck that left two Hilton Head Island High School seniors dead, according to the 14th Circuit Solicitor's Office.
Solicitor Duffie Stone said Thursday the results of evidence testing by the S.C. Law Enforcement Division will help prosecutors determine whether to charge driver Ramon Morales, who was 18 at the time of the fatal wreck.
Stone declined to say what evidence was being tested and did not know when the testing would be completed.
Passengers Cory Rocha, 18, and Cesar Herrera, 17, were killed, and Michelle Alvarez, then 16, was injured when Morales' Ford Fusion ran off Dillon Road and struck an embankment and a tree, according to the S.C. Highway Patrol.
Morales suffered severe injuries as well, troopers said.
A report by the patrol's Multi-disciplinary Accident Investigation Team completed in late May found the wreck was primarily caused by aggressive driving and Morales reaching speeds of about 115 mph on the two-lane road.
