Nevada woman charged in July crash that killed four in California family

MINDEN -- A 42-year-old Gardnerville woman has been charged with reckless endangerment in connection with a July head-on collision that killed four members of a Torrance, Calif., family.

According to the criminal complaint, Dawn Miley's vehicle crashed on U.S. Highway 395 south of Gardnerville after she self-medicated her diabetes without supervision of a physician.

As a result of the self-medication, her level of consciousness was altered by low blood sugar, causing her to lose control of the vehicle, the complaint alleges.

Investigators subpoenaed her medical records from two Carson City doctors who said they warned her of the dangers of failing to monitor her condition under a physician's supervision.

After moving to the Carson Valley in 2005, Miley said she was unable to maintain medical insurance, so she decided to treat her diabetes with over-the-counter drugs, according to court documents.

Miley said she tests her blood sugar and injects herself four times a day.

Jerome Calvero, 58, his wife, Maria, 52, and their two children, Bernadette, 23, and Jerome, 15, were killed in the accident.

Miley was southbound when her sport utility vehicle drifted off the highway and struck a road marker, the Nevada Highway Patrol said. The vehicle then crossed into oncoming traffic, striking the Calvero family's pickup.

All four family members were pronounced dead at the scene, authorities said.
