The Oklahoma State Bureau of Investigation (OSBI) told Fox News Digital that "it’s becoming more and more challenging" to find Veronica Butler and Jilian Kelley alive as the days mount with no signs of the missing Kansas women's whereabouts.
OSBI public information manager Hunter McKee made the comment Tuesday as it has now been 10 days since the women vanished while traveling to pick up children. Investigators say their vehicle was found abandoned on March 30 in a rural area of Oklahoma and "foul play" is suspected.
"It’s a lot of land. Middle of nowhere, so searches still are continuing," McKee said. "We still are working on talking with multiple people and hopefully we can find something soon."
"It’s been over a week," he added. "We are hopeful that we can find them alive, but obviously it’s becoming more and more challenging."
The OSBI announced last Thursday that "Based on the information obtained from the victim’s [abandoned] vehicle, our investigators believe there was evidence to indicate foul play."
A missing persons advisory from the Texas County Sheriff’s Office said that Butler has "several tattoos, a Chinese symbol on her left forearm, a sunflower on her left shoulder" and that "Jilian has a butterfly tattoo on her left forearm."

The alert describes Butler as being 5 feet, 4 inches tall with red hair and green eyes, last seen wearing a blue short-sleeve shirt and denim shorts.
Kelley has brown hair and blue eyes and was last seen wearing a long-sleeve shirt, blue jeans and tan or beige shoes, the alert adds.
The vehicle they were traveling in was "found abandoned near Highway 95 and Road L, south of Elkhart, Kansas, in rural Texas County," according to the OSBI.
