Turpin family: 13 captive siblings forced to shower once a year, tortured, strangled, subject to frequent beatings: Prosecutor Says (videos) Parts, 1 -7 

The California parents accused of holding their children captive allegedly forced them to shower only once a year, never took them to a dentist, and strangled and beat them routinely, prosecutors said Thursday.

David Turpin, 57, and Louise Turpin, 49, were arrested on charges of torture and child endangerment after their children were found Sunday at their home. The Riverside County Sheriff's Office described the residence as "dark and foul-smelling."

The Turpins both entered not guilty pleas on all counts Thursday. Their next court date was set for Feb. 23.
