Relatives and friends of a California family who lost four members in a recent suspected DUI crash involving two other vehicles saw their heartbreak worsened this week by a break-in at the family's home, according to reports.

Killed around 5 a.m. Nov. 20 on Interstate 80 in Nevada County were parents Antonio and Brittney Montano, both 29, daughter Marianna, 9, and son Antonio Jr., 5, authorities said.

The surviving child, son Julian, just 4 years old, suffered multiple fractures as well as head trauma. He was expected to recover and an aunt and uncle of the boy plan to adopt him, FOX 40 of Sacramento reported.

The family had been on the road to celebrate the mother's birthday and the upcoming Thanksgiving holiday, reports said. But an alleged drunken driver traveling the wrong way on the interstate turned their outing into a tragedy.
