CHARLESTON, W.Va. (WSAZ) -- A mother from Kanawha County who faces murder charges in the death of her son is headed back to jail.

A judge revoked Stephanie Raines' bond Friday after she pleaded guilty to violating the terms of her home confinement by failing a drug test.

Prosecutors say she was stealing Darvocet from her grandfather who is sick, but the defense claims she was given the pills after she was involved in a car accident. Raines is approximately six months pregnant.

Raines was originally charged with neglect causing death, but earlier this year she was indicted on murder charges.

Two years ago Raines' son Jacob died at her house in Dunbar. He was just three months old.

Raines was sent straight to jail on Friday.

Jerry McFarland is also charged in the case.

Raines and McFarland are scheduled to go on trial next month.
