Deputies from the Jacksonville, Florida Sheriff's Department visited West Virginia as part of their investigation into the death of an 11 year old girl.
The West Virginia Highway Patrol reports that Newsome stated she had picked up her daughter, Kaye-lea Plummer, on Friday.
Plummer told the news station he believed his estranged wife "snapped" and that she'd been "the only person I trusted with my child".
"It was obvious that the 11-year-old did not die from injuries from the accident", Barlow told the Pocahontas Times.
West Virginia State Police say Erica Newsome crashed her auto Sunday morning in the Allegheny Mountains, and witnesses reported they saw her trying to hide her daughter's body by a hill.
Police said they soon found 37-year-old Erica Newsome, along with the body, on an old logging road.
"Something pushed her over the edge and she snapped", he told News 4 Jax.
"The child was placed in the vehicle early Saturday morning and she headed toward Buffalo, New York", Barlow said.More news: A 9/11 Victim Has Been Identified 16 Years After the Attacks

According to Plummer, the Mother, Erica Newsome told him that Kaye-Lea and Newsome were on the way to see him in Buffalo, New York.

The body of the deceased child was discovered Sunday after a auto wreck on a remote stretch of U.S. Route 250 in Pocahontas County just over a mile from the Virginia border.
"She just always brought a smile to my face, no matter how I was feeling". 'Something is very, very wrong.
