FREDERICK, Colo. – The Latest on the arrest of a Colorado man in the disappearance of his family (all times local):
A lawyer for a Colorado man suspected in the deaths of his pregnant wife and two young daughters says the daughters' bodies were submerged in crude oil for four days before they were found.
Defense attorney James Merson made the statement in a court motion Friday. The motion asks a judge to order that DNA samples be taken from the children's throats.
In another motion, Merson asks that DNA samples be taken from the hands and nails of the body of the girls' mother.
It wasn't immediately clear if the judge ruled on the motions.
Thirty-three-year-old Christopher Watts was arrested Wednesday on suspicion of three counts of murder. On Thursday, investigators found the bodies of his wife, Shanann Watts, and their daughters, ages 3 and 4.

Violent crimes have prompted debate before in Colorado, including in 2015 after a woman cut open a pregnant woman's belly and removed her unborn baby.
Proposals to change the law have been stymied by debate about when a fetus can legally be considered a human being.
Colorado does allow a homicide charge if a fetus was alive outside the mother's body and then killed.
Shanann Watts painted a rosy portrait of her family on Facebook, calling her husband and the father of her two young daughters her "rock" and writing that he was "the best dad us girls could ask for."

Shanann Watts, who was pregnant, and the couple's 3-year-old and 4-year-old daughters were found dead in northern Colorado on Thursday.
