Investigators are examining the vehicle and surrounding area for evidence that could help determine exactly what happened. Witnesses are also being questioned as authorities work to establish a timeline and compare accounts from people who may have seen or heard the incident.
So far, officials have not announced a possible motive or identified a suspect. Authorities caution that early information may change as additional evidence is collected and are asking people to avoid spreading unconfirmed details while the investigation remains active.
Anyone with information that could assist investigators is being encouraged to contact law enforcement. Officials have not indicated that there is a broader threat to the public at this time. Additional information is expected to be released once details are verified and the investigation progresses.
