The man who killed two teenagers behind a Roswell grocery store has been moved to Valdosta State Prison. But the Georgia Department of Corrections declined to confirm whether the move was related to Jeffrey Hazelwood’s recent Instagram post, made using a contraband cell phone.

“...GDC regularly moves inmates around the state based on numerous factors, including needs, bed space, etc.,” a spokeswoman wrote in an email Tuesday morning. “Reasons for specific moves are part of the offender’s institutional file, and therefore not subject to disclosure.”

Hazelwood, 21, was previously being held at Baldwin State Prison, just outside of Milledgeville. Earlier this month, he was able to post a "selfie" on social media from inside the prison, The Atlanta Journal-Constitution reported. The investigation began after the AJC asked prison officials about the image.

Last week, a prison spokeswoman said investigators had not determined how Hazelwood got the phone, but that he would be disciplined.

In May, Hazelwood pleaded guilty but mentally ill to murdering Natalie Henderson and Carter Davis, both 17, and was sentenced to life in prison.
