Eleven-year-old Isabelle Tezsla was killed in the crash.
Tests have concluded that neither drugs nor alcohol played a role in a bus crash in southern New Jersey that killed an 11-year-old girl.
Burlington County Prosecutor Robert Bernardi and Chesterfield Township Police Chief Kyle Wilson announced the results today. They showed bus driver John Tieman and dump-truck driver Michael Caporale weren't under the influence of alcohol or illegal drugs at the time of the Feb. 16 crash.
Eleven-year-old Isabelle Tezsla was killed, while her sisters, Sophie and Natalie, and 11-year-old Jonathan Zdybel were all hospitalized with serious injuries.
Police have issued motor vehicle citations to both drivers and to Caporale's trucking company.
The prosecutor's office says it will await the National Transportation Safety Board's final report on the accident before it decides whether to file criminal charges.
