The incident happened shortly after 1:30 a.m. Sunday in the 1500 block of North San Antonio Avenue.
Police arrested the driver, 20-year-old Raelene Martinez of Ontario, on suspicion of driving under the influence. She is also facing a charge of manslaughter. Investigators are also looking into whether racing may have been a factor.
Investigators say Martinez was traveling northbound on North San Antonio Avenue when she lost control of her 1995 Toyota Camry. Her car rolled over after slamming into several parked cars. One female passenger was pronounced dead at the scene, while Martinez and three other passengers were transported to local hospitals for treatment of non-life-threatening injuries.
