A tragic incident unfolded in California when a pregnant woman, on her way home from In-N-Out Burger after indulging in a craving, was struck and killed by a drunk driver who ran a red light. Authorities and her boyfriend reported that the victim was expecting her second child and leaves behind a 4-year-old son, as confirmed by her grieving family.

Viri Esquivel, the sister of 24-year-old Bianca Esquivel, expressed her heartbreak during an interview with local ABC affiliate KABC. She shared the painful challenge of explaining to Bianca’s young son, “Where’s my mommy?” knowing that “his mommy isn’t coming back.”

The suspect, 24-year-old Daniel Ramos, is now facing serious charges of felony DUI and vehicular manslaughter following the crash that occurred in Anaheim, as reported by KABC. Bianca and her boyfriend, Oscar, who requested his last name be withheld, were returning home after a trip to In-N-Out to satisfy Bianca’s pregnancy cravings.

Recalling the moments leading up to the crash, Oscar shared with KABC, “We were laughing on the way back, just smiling.” The joy was shattered in an instant as Bianca exclaimed, “Oh my god,” before the fatal collision.

Oscar, reflecting on their shared life, described Bianca as his best friend. “We were so excited,” he recalled. “We were already planning things, buying clothes.”

Police say Bianca Esquivel was a passenger and Oscar was driving when Ramos slammed into them at the intersection of North Anaheim Boulevard and the 91 Freeway frontage road. Viri Esquivel told KABC she rushed to the scene after her phone detected a crash via Bianca’s emergency contact setting.

“I was her emergency contact on her cellphone, so the SOS detected a car crash, and it gave me the exact location,” Viri Esquivel said, noting that her sister “was very excited with her second child.”

Ramos, who was driving with two passengers, is accused of running a red light in his Lexus sedan before slamming into the Toyota sedan that Oscar and Bianca Esquivel were in. Bianca was found trapped in the Toyota and was pronounced dead at the scene.

“Due to the victim being pregnant, additional charges may be considered pending the outcome of the investigation,” Anaheim police said in a press release. The district attorney’s office is probing the case.

“Bianca was a devoted mother, a beloved sister and daughter, and a caring girlfriend,” a GoFundMe explains. “She was preparing to return to school to pursue a degree in accounting and had her entire life ahead of her.”
