University student Jacqueline Vandagriff, 24, was last seen leaving a bar with gym instructor Charles Dean Bryant, 30, in Grapevine, Texas, on September 13.

However police are now investigating a series of posts sent from the victim and the accused’s social media accounts following the senseless killing.

The Sun reports that after Vandagriff’s body was found on September 14, someone posted an eerie message on her Twitter feed the next day, which read: “Never knew I could feel like this.”

On the same day Bryant, who now faces the death penalty, posted this message on his Facebook page: “Full moon, let’s see what trouble I can get into.”

Court documents reveal that Vandagriff’s smartphone was found near Bryant’s home on the day her body was discovered.

Her burned remains were found in Grapevine after firefighters were called to a blaze in Acorn Woods Park at 6:30am last Wednesday.

Vandagriff, of nearby Frisco, had met Bryant in a bar the previous evening.

Police Sgt. Robert Eberling said detectives used CCTV footage of the pair to identify the 30-year-old suspect and track him down.

He was arrested on Sunday after a statewide search which included FBI officers and has been charged with capital murder with a $1 million bail.

The gym instructor was picked up by police near his house in Haslet in the outskirts of Fort Worth.

The Vandagriff family released a statement thanking the “extraordinary efforts” of investigators and wellwishers.

“We would also like to thank our friends, family and the friends of our daughter Jackie for all their support in this difficult time,” the family said.

Ambitious Ms Vandigraff was in her first year at Texas Women’s University in Denton, where she was studying nutrition.

A video CV uploaded by Jackie last year shows how eager she was to begin in her chosen career path.

The school’s Vice President for Student Life Monica Mendez-Grant paid tribute to Vandagriff in a statement.

“The death of a student affects the entire TWU community, and I know that all of us send our deepest sympathy to Jacqueline’s family and friends”, she said.

“Jacqueline exemplified the spirit of learning and service that is the hallmark of our TWU community.

“She lived her life with a desire to serve others through her interest in nutrition.”
