The attorney general's office says 53-year-old Robert Dellinger of Sunapee recklessly killed 24-year-old Amanda Murphy and 29-year-old Jason Timmons of Wilder, Vt. The say he crossed over the center line Saturday on Interstate 89 in Lebanon and crashed head-on into the couple's SUV.
Murphy was eight months pregnant.
Dellinger - who was hospitalized after the crash - will be arraigned in Lebanon District Court at 3 p.m. Wednesday on two counts of reckless manslaughter.
It was not immediately known whether he has a lawyer. A man who answered the phone at Dellinger's home Tuesday declined comment.
