A mother, Becky Tollan, has died after doing cocaine on first night out after birth of baby

 A new mom died after taking cocaine on her first night out following the birth of her baby, a UK court has heard.

Becky Tollan, 23, died at a house in Lanarkshire, Scotland, July 15, 2019, after partying with her sister-in-law and two men they met at a local pub.

The men — Barry McAuley, 40, and Martin Stewart, 34 — have been charged with culpable homicide after allegedly providing Tollan with the Class A drug.

The duo’s trial began Wednesday, with Tollan’s sister-in-law, Pamela Tollan, taking the stand to recall the brunette’s tragic death.

Pamela told the court that her sister-in-law had abstained from drugs and alcohol during her pregnancy and that her body may have been overwhelmed on her first night out after giving birth.

McAuley and Stewart have both pled not guilty to the culpable homicide charge. The trial continues.
