A man and a woman, who were believed to be undocumented, died after their vehicle crashed while they fled from federal immigration officials in California on Tuesday, police said.

Marcelina Garcia Profecto, 33, and Santo Hilario Garcia, 35, initially stopped after a vehicle flashed its emergency lights to pull them over, but fled once they saw federal agents from Immigration and Customs Enforcement (ICE) exit the vehicle, police in Delano, Kern County, posted on Facebook.

The driver sped off and lost control shortly after driving onto the dirt shoulder, where the vehicle overturned and struck a power pole, police said.

The couple were pronounced dead at the scene. They leave behind their six children between ages 8 and 18, Fresno’s Fox 26 reported.
