Three of the children were missing, though the body of a girl believed to be one of the missing children was found near the site of the accident last week.
Police hadn't found the bodies of Devonte Hart and his adoptive sisters, 16-year-old Hannah Hart and 12-year-old Sierra. The body has yet to be identified.
Sarah Hart and two of the three children found dead at the scene tested positive for diphenhydramine, an active ingredient in Benadryl.
At some point between the family's last sighting that night and March 26, when their SUV was found at the bottom of the cliff - likely several hours after landing there - it appears Jennifer Hart had a few drinks.
Preliminary toxicology tests found Jennifer Hart had an alcohol level of 0.102, said California Patrol Capt. Bruce Carpenter.
Shanaaz Jacobs, 19, who lived with her parents and siblings in Uitenhage, has finally spoken out after her family alleged that her boyfriend, Pakistani national Warqas Khan, whom she met previous year while he was in South Africa, was preventing her from returning home.
He said in the "interest of transparency and accountability", police should release all video they have of the last week's shooting to the public, or at least to the family. It means that caregivers must try to see things from their parent's view and remember that one day they may be facing these same challenges.
Jacobs has accused her parents of causing "unnecessary drama" in her life - and said she had attempted suicide because of it.

And authorities have said social services officials in OR contacted the West Linn Police Department about the family in 2013 while they were living in the area.
"I asked her why she's doing this because she's destroying my whole reputation - not only mine, but my [Pakistani] family's reputation too". I am 19 years old and I came here because I want to be here and stay [in Pakistan].
Officials said they have searched the family's home, as well as the couple's bank and credit card statements and phone records. Earlier the authorities announced they were able to locate numerous items that appeared to have come from the vehicle belonging to the missing family.
The friend said that perhaps it worked out for the best, because if Marcia had called her, maybe the gunman would have killed two of them, because they would have been together.
