The Riverside County Sheriff's Department said in a Jan. 15 news release that the siblings, ranging in ages from 2 to 29, "appeared to be malnourished and very dirty." Six of the siblings are minors.

Riverside County District Attorney Mike Hestrin said David Allen Turpin, 57, and Louise Anna Turpin, 49, were charged with 12 counts of torture and a lewd act on a child by force or fear of duress. The siblings could only have one meal a day and take one shower a year. Hestrin said at a news conference that the siblings were able to write in journals all the time, which will provide "strong evidence of what occurred in that home."

Two dogs were found by authorities in the home, according to city spokesman Joe Vargo. Vadrgo said in a statement that the two Maltese terrier dogs were in much better condition than the siblings.

“The animals, one white and one black, appear healthy and friendly and are leash-trained, according to Christina Avila, a senior animal control officer,” a news release from the City of Perris said.

The parents made their first court appearance Thursday and entered not guilty pleas to all charges. Their bail is set at $13 million. They are scheduled to appear in court again Feb. 23.
