The cause of a crash on St. Helena Island last month that killed two Beaufort High School students and critically injured another has yet to be to determined, authorities say.
The S.C. Highway Patrol's Multi-Disciplinary Accident Investigation Team is continuing its probe of the one-car crash April 21 on Seaside Road that killed Chelsie Nicole Teddy Pitruzzella , 18, and Kayleeana Hudson-Banks, 15, said Cpl. Bob Beres.
Beres declined to say whether investigators had reached any preliminary findings.
"All I can tell you is that the entire collision is still under investigation," he said.
Beres said the agency will release a report on the crash after the investigation is complete, though he did not know when that would be.
Pitruzzella, a senior at Beaufort High, and Hudson-Banks, a sophomore at the school, were killed when the 2009 Mitsubishi sedan Pitruzzella was driving veered off the left side of Seaside Road, overturned and struck a tree, according to the Highway Patrol.
A third passenger, Megan Trimmer, 16, also was injured in the crash. She was airlifted to Memorial University Medical Center in Savannah, authorities said.
An update on her condition was unavailable Friday.
All three girls were wearing seat belts, according to the patrol.
