Isaac Moses Casares, 19, of Ontario, the alleged driver, was arrested on suspicion of driving under the influence causing injuries, felony hit-and-run and assault with a deadly weapon. Shortly after midnight Friday, police received a 9-1-1 call reporting three women had been hit by a vehicle in the 600 block of West La Deney Drive, according to a police news release.
Officers and Ontario firefighters found three women lying in the street suffering from minor injuries, officials said.
One of the women had been arguing with her boyfriend, 18-year-old Matthew Rodriguez of Hacienda Heights, shortly before the incident took place, said police Sgt. Jeff Higbee.
Rodriguez, his 19-year-old girlfriend, her 21-year-old sister and the women's 38-year-old mother were all outside when the argument broke up, according to authorities.
Rodriguez reportedly got into a black Honda Civic driven by his friend, later identified as Casares, and Casares allegedly sped toward the women, striking them, police said. Casares drove away but was located a short time later and taken into custody, police said. Rodriguez was also detained.
Paramedics took the women to Arrowhead Regional Medical Center in Colton. Their condition was unavailable.
After an investigation, Rodriguez was released.
Casares was booked into West Valley Detention Center in Rancho Cucamonga. He is scheduled to be in court on Tuesday.
