FORT WORTH, Texas (AP) - A toxicology report issued Wednesday indicates no over-the-counter medicines, illegal drugs or alcohol were in the bodies of four hanging victims.
Investigators believe a woman hanged her three girls, then committed suicide, at the family's mobile home in Hudson Oaks. That's about 25 miles west of Fort Worth.
A fourth girl -- an infant -- survived last week's hanging.
The Tarrant County Medical Examiner reports the bodies of Gilberta Estrada and her daughters tested negative for alcohol, cocaine, opiates, amphetamine and other drugs.
The triple murder-suicide ruling in the May 29 deaths remains unchanged. Authorities do not suspect foul play in the deaths.
The only survivor was eight-month-old Evelyn Frayre, who wasn't
seriously injured and is now in foster care.
A hearing is next week on which relative can best care for the baby.
