(ST. MARY, Mo., AP) — A southeast Missouri woman is facing charges for the drug overdose deaths of two men.

The Southeast Missourian (http://bit.ly/1doPAPj) reports that 56-year-old Sandra M. Dallas of St. Mary is charged with two counts of first-degree involuntary manslaughter and drug charges. She is accused of supplying methadone to 42-year-old Travis Welty and 55-year-old Darin Reid on Oct. 19, hours before the men died.

Authorities say Dallas was showing the men a trailer she was trying to sell. They reportedly began discussing drugs and she allegedly sold the men methadone. A toxicology report showed that both men tested positive for methadone.

A phone call on Thursday seeking comment from an attorney for Dallas went unanswered.
