RICHARDSON (CBSDFW.COM/AP) – A jury has found Jason Lowe, 28, guilty of killing his girlfriend in May 2016. Police found Jessie Bardwell’s body in a field near Farmersville.

He was sentenced by the judge to a maximum of 50 years in prison.

Lowe testified he and Bardwell took the mind-altering drug GHB before having sex in a shower, where she fell and struck her head.

Prosecutors said they didn’t believe Lowe’s version of events.

Evidence at trial showed her body was stored for some days in his vehicle.

Officers stated that cell phone data and some good detective work led them to Bardwell’s body, in a remote wooded area off of Highway 78.

The 27-year-old woman’s body had been there for days.

Lowe was also facing drug charges after officers discovered cocaine inside of his apartment. He had been arrested in 2015 for aggravated assault causing serious bodily injury.

According to an affidavit, he allegedly attacked his former girlfriend, causing her to lose consciousness.
