Two people were killed early Sunday in a fiery crash in northwest Indiana.

Shawn Robb, 39, and 38-year-old Alisha Robb, both of Hobart, were in a blue 2013 Chevy Equinox going west about 12:20 a.m. on US Hwy 12 when they veered off the road and struck a tree just east of Tremont Road near Chesterton in Porter County, according to the Porter County Sheriff’s Office.

The Chevy became fully engulfed in flames. Both suffered severe burns and died inside the car, according to the coroner’s office.

Authorities are investigating the crash.
