A Texas woman has been arrested after she allegedly tried mailing meth to a double murderer serving a life sentence in prison.

Sara Elizabeth Russell, of Katy, was taken into custody on Thursday after a mailroom worker at the James V Allred Unit prison spotted a bulge behind a photograph.

The photograph was attached to a handmade card. When the worker pulled on the photo, she discovered a clear package filled with a white powder.

Tests later revealed that the white powder was methamphetamine.

Also included with the package were handwritten instructions on how to disguise the meth in the card, according to KFDX.

Part of the instructions included a note to tape the outside edges of the package shut.

Inmate Jason Burkett told investigators that he had made the card and mailed it to Russell but claimed he did not ask her to mail him drugs.

The Texas Department of Public Safety Crime Lab tied fingerprints on the package back to Russell.

Russell has been charged with one count of prohibited substance in a correctional facility. She is being held on $10,000 bond.

Burkett is serving a life sentence for his involvement in a gruesome triple murder in 2001.

He was found guilty of killing two teenage boys. His co-defendant, Michael Perry, was executed for murdering the mother of one of the victims.
