A tragic incident in California claimed the lives of a pregnant woman and her unborn child after a suspected DUI driver collided with her vehicle over the weekend.

Bianca Esquivel, 24, who was expecting her second child, lost her life in a crash that occurred in Anaheim, near Los Angeles, around 12:04 a.m. on Sunday.

Daniel Ramos, 24, from Riverside, has been taken into custody, facing charges of felony DUI and vehicular manslaughter.

The unfortunate event took place at the junction of North Anaheim Boulevard and the SR-91 freeway, according to a statement from the Anaheim Police Department.

Prior to the collision, Esquivel and her boyfriend, Oscar, had visited an In-N-Out Burger to satisfy a pregnancy craving and were on their way back home.

Oscar, who was hospitalized following the crash, recounted that Esquivel screamed as another car seemed to appear suddenly before colliding with them.

‘We were laughing on the way back, we were just smiling,’ he told ABC7. ‘It was so fast.’

‘She was my best friend,’ Oscar continued, adding that they were ‘excited’ to welcome their second child. ‘We were already planning stuff, buying clothes.’

Anaheim Police detectives believe that Ramos’ Lexus Sedan ran a red light before striking the couple’s Toyota at a high speed. 

Ramos ‘exhibited objective signs and symptoms of impairment’, the department said. 

He was arrested at the scene, and appeared dazed in his mugshot. 

Photographs from the scene show a crumpled Toyota vehicle, which officers found Esquivel trapped inside when they rushed to the highway.

‘Bianca was a devoted mother, a beloved sister and daughter, and a caring girlfriend,’ the page reads. 

‘She was preparing to return to school to pursue a degree in accounting and had her entire life ahead of her.’
