Police have identified four of the six people killed in a plane crash at the Bangor Airport last month.

Bangor police said the medical examiner’s office identified four of the victims as Tara Arnold, Jordan Reidel and Jacob Hosmer, all from Texas, along with Shelby Kuyawa of Hawaii.

The medical examiner’s office is still working to confirm the identities of the other two people on board.

Some of the victims had already been identified by family members.

Federal investigators are looking into what caused the private jet to crash while trying to take off during a snowstorm, ending up upside down and on fire.
