UPDATED: A single vehicle collision resulted in the deaths of two young women early Saturday morning. The two deceased victims, both passengers, were identified as Joanna Munoz, 19, and Monique Magana, 20, both from Upland. Ms. Munoz was pronounced dead on scene. Ms. Magana was transported to a local hospital before reportedly dying from her injuries. A third occupant, an 18-year-old female, from Upland, was transported to USC Medical Center with moderate injuries.

Investigation determined that the driver, Artisha Wright, 21 years old, from Upland, was driving under the influence of alcohol. Police are waiting on the crime lab report to determine her blood alcohol content. Ms. Wright was arrested for gross vehicular manslaughter and driving under the influence resulting in injury. She has since posted bail and is due back in court on March 5. Police say the maximum sentence is four years with a low of 16 months.

Police say the women had been in Ontario earlier in the evening and were headed east on Foothill Boulevard when the car crashed into an electrical pole in the 300 block of the main city thoroughfare. Alcoholic beverages were reportedly found in the center console of the vehicle, and an alleged fight had broken out just before the crash. Investigation continues.
