Overland (USA) - A woman from the US state of Missouri will soon have to stand trial. The reason: she is to blame for the death of her 14-year-old daughter.

As People reported, the teenager died last month, on October 3. An autopsy revealed that she had a fatal amount of fentanyl in her blood.

But how could this have happened?

The 14-year-old had previously complained to her mother, Jacquelyn Renee Powers, about toothache. To help the child, Powers had immediately taken action and given her "a pill" that she had "found in one of her drawers".

She told police that she believed it was the painkiller oxycodone, which she had recently been given herself after she had undergone surgery.

About ten hours later, her daughter was dead. According to the autopsy, she tested negative for oxycodone.

When asked about this by the officers, Powers stated that she had swapped her painkillers for pills that her own mother had bought on the street some time ago. So she only wanted to "protect her mom from the dangerous pills".

So far, it is unclear whether she deliberately gave the 14-year-old the drugs, whether the swap actually took place and, if so, why she gave her daughter the pills anyway.

"It's tragic," lead investigator Jim Morgan told Fox 2 Now, "something like this shouldn't happen."

Power is currently in custody and will appear in court for the first time on December 1. The charges: endangering the welfare of a child in the first degree and death of a child. If she is found guilty, she faces a life sentence.
