Santa Monica police have arrested four suspects in connection with the robberies of two female students who were on their way to school Oct. 21.

At about 9:10 a.m. a 16-year-old student had parked her car in the 2000 block of Sixth Street in Santa Monica and was walking to school when a vehicle approached her. A female suspect got out of the vehicle and allegedly demanded the student’s belongings, but as the suspect reached for the items, the victim blocked her hand, Santa Monica police Sgt. Jay Trisler said.

The suspect then allegedly stabbed the student in the face with a sharp object, resulting in a quarter-inch puncture wound, and fled the area with the victim’s purse and cell phone, Trisler said. The 16-year-old was treated at a local hospital and released.

Approximately 10 minutes later, another student was walking to Santa Monica College when a male suspect approached her at Euclid Street and Michigan Avenue. The suspect allegedly displayed a knife, demanded the student’s belongings and then fled with her purse and cell phone in a vehicle, Trisler said.

Police obtained the vehicle’s license plate number and were able to locate the car in South Central Los Angeles at 10 p.m. that night, Trisler said. After police allegedly recovered property of both student victims inside the vehicle, they arrested four suspects.

The suspects, who are all from Los Angeles, were identified as Mary Montes, 18, Roberto Rodriguez, 28, Crystal Marquez, 20, and a 17-year-old juvenile, Trisler said.
