/*Tiffany Denise Reynolds*/, the 26-year-old Richmond woman who is suspected of driving the vehicle under the influence, fractured her neck and severely hurt her chest, and is stable today, according to the CHP.
Reynolds, who was the mother's domestic partner, allegedly lost control of the 1990 Honda Accord on northbound Interstate Highway 880, traveled across multiple lanes and crashed into a concrete wall near Hegenberger Road around 1:30 a.m. Monday, CHP Officer Sam Morgan said.
Twins Jason and Jessie Woodson of Richmond were not restrained during the crash and one of them had been ejected and the other was found pinned beneath the steering column, CHP Officer Sam Chase said.
Officers did not see car seats.
Their mother Sara Marie Terra, a 23-year-old Richmond woman, and her 20-year-old brother David James Terra of Modesto, were pronounced dead at the scene, Morgan said.
One of the twins died at Children's Hospital Oakland the same day around 9:30 a.m. and the other died today just after noon, according to the Alameda County coroner's bureau.
Reynolds was scheduled for an arraignment today on suspicion of felony driving under the influence, gross vehicular manslaughter and driving on a suspended license, according to the Alameda County District Attorney's Office.
