Federal safety officials will investigate a Mississippi crash that killed eight people.

The head-on collision between a box truck and a passenger van happened before dawn Monday on Mississippi 16 east of Scooba.

The National Transportation Safety Board said Wednesday that it’s sending one investigator to look into technology on the 2020 International Harvester Corp. Box Truck and any potential contributing factors.

Weather isn’t believed to have contributed.

Andy West of the Mississippi Highway Patrol says the eight men killed were Guillermo Lugo, Francisco Lugo, David Lugo, Luis Lugo, Macario Peregrino, Jose Maldonedo, Arnulfo Martinez and Jose Barrera. The Lugos were brothers. All lived in Macon, Mississippi.

Both drivers survived. The van driver was Alejandro Resendiz, also of Macon. The truck driver was Steven McKinney of Good Hope, Alabama.
