Authorities in Texas say a woman killed her roommate and set their residence on fire following an argument over the victim’s text messages to the suspect’s former romantic partner.

According to the Dallas Morning News 21-year-old Kristen Elizabeth Jones was arrested shortly after noon on Monday near Gainesville after spending the previous several hours searching for her.

Emergency personnel responded to the scene of a residential fire near Luther, Oklahoma, at around 9:30 a.m. Monday.

An investigation indicated Jones was identified as a suspect in what they say was arson to cover up her roommate’s homicide death.

The Oklahoman cited an affidavit submitted in connection with the arrest warrant, which alleges the suspect engaged in a physical altercation with 23-year-old Miranda Pederson. Jones allegedly confronted the victim in anger over texts between Pederson and Jones’ ex.

Bryson Harrington, the man in question, also reportedly lived at the residence.

Reports indicate the suspect’s mother and Harrington called Jones and allowed investigators to listen to their conversations.

The suspect allegedly admitted stabbing Pederson in the chest, retrieved a firearm from a bedroom and shot the victim in the back of her head.

She said she was overcome by fear and decided to set the home ablaze, according to police reports.

Oklahoma authorities received a tip that the suspect had traveled to Texas. Jones was later apprehended in Cooke County during a traffic stop along Interstate 35.

She is expected to face charges including murder, arson and desecration of a human corpse. As of the latest reports available, she was being held in Oklahoma County jail without bond.
