Authorities Friday investigated a possible link between two toddlers found abandoned and the discovery of two unidentified women who were bludgeoned to death.

A gas company employee inspecting gas lines found the bodies, which were covered with a blanket, at about 9:45 a.m. Thursday near a cattle guard in a culvert, about 2 miles east of Decatur in north Texas, authorities said.Both women, who were of Asian descent and in their 20s or 30s, had suffered blows from a blunt instrument that resulted in cerebral hemorrhages, a Tarrant County medical examiner's autopsy report showed.

Wise County sheriff's Capt. Roy Alexander said one victim's feet had been bound and she had been partially scalped.

Wise County Sheriff Leroy Burch and Texas Ranger Phil Ryan were in Denton, about 27 miles east of Decatur, Friday morning to investigate possible links with the two toddlers, who were found abandoned about 5 miles apart Thursday, and the murder victims.

Denton County Sheriff Kirby Robinson said the children also appear to be either of Hispanic or Asian descent. He said the boy and girl are believed to be 9- to 12-months old and were found wearing only diapers.

Robinson says the two were in good condition and placed with foster families in Denton.

The Tarrant County medical examiner's report said the women were killed about 3 a.m. Thursday. Alexander said neither victim was wearing shoes or jewelry.
