Video shows amused officers abusing California woman

Mexican police officers have been charged in the death of a California woman in a Baja jail cell.

An investigation by the Spanish-language sister station of KSND-TV in San Diego also revealed three others will face charges tied to conspiracy to cover up the death of Paulina Baeza, 20, a college student in Irvine, Calif..........

A surveillance video from inside the jail shows Baeza being carried and dragged by officers a short time before she was reported dead, KSND reported.

An officer can be seen grabbing Baeza by her hair in the video. Another one is shown laughing, and one office appears to draw his finger across his throat, then dances as the girl is hauled away, the TV station said.
