(CNN) A motorist who struck a pedestrian drove almost a mile with the man's body lodged in the windshield, his head resting on the passenger seat, police in Oceanside, California, said Tuesday.

One witness told CNN affiliate KGTV he was changing the oil in his car when he witnessed the gruesome crash.

"There's no words to really describe it. I mean, just seeing that up close and personal, it's kind of traumatizing in a way," Edwin Esparza said.

Oceanside police said the woman, Esteysi Sanchez, 29, was driving home around 6:20 a.m. Monday after a night of drinking. She started to swerve on Mission Avenue and struck a pedestrian, police said.
