A woman and her three young daughters have been found fatally shot in the head in rural eastern Missouri.
Names of the victims have not been released. The bodies were found early Thursday at a home near De Soto, about 45 miles south of St. Louis.
The 32-year-old woman was found dead on steps leading to the porch. The girls, ages 1, 10 and 11, were found inside a van. Jefferson County Sheriff Glenn Boyer says all four were shot in the head.
Boyer says detectives are questioning the woman's estranged boyfriend who lived at the home where the bodies were found. He says the mother had a restraining order against the boyfriend.
Boyer says detectives are also investigating the possibility of murder-suicide.
