RICHMOND, Calif. -- A second suspect in the brutal rape and beating of a 15-year-old Richmond High student after a homecoming dance was taken into custody by police Monday as the investigation into what the Richmond Police Chief described as a sickening crime continued.

"She was raped, beaten, robbed and dehumanized by several suspects who were obviously OK enough with it to behave that way in each other's presence," said Lt. Mark Gagan, a patrol supervisor in the city's Northern Policing District. "What makes it even more disturbing is the presence of others. People came by, saw what was happening, and failed to report it."

Ortega remained at Contra Costa County Jail in Martinez on Monday, booked on suspicion of rape and robbery. Detectives believe as many as six other men raped the girl as she lay semiconscious on a courtyard bench, also beating her, taking pictures and stealing her jewelry.

"As people announced over time that this was going on, more people came to see, and some actually participated," Gagan said
