Three women found dead in an Akron, Ohio, home last week possibly overdosed on fentanyl, one of the women’s mothers revealed.

Per the Cleveland Scene, girlfriends Ashtyn Andrade and Tara Williams had invited Courtney Collier to their home Friday to celebrate Andrade’s 20th birthday. Police found the three women dead Saturday night after Collier’s mother and boyfriend called and requested a welfare check when she didn’t turn up for work.

According to the medical examiner’s office report, the three women were found unresponsive on the living room floor and pronounced dead at the scene. Investigators reportedly found two straws, a dollar bill, and an unknown powder residue in the kitchen.

Andrade and Williams had relocated from Arizona to Akron six months earlier and were engaged to be married. Williams had worked with Collier at McDonald’s. Andrade’s mother, Joanna Andrade, said police told her that the 20-year-olds possibly overdosed on a fentanyl mix.

“People are starting to lace things with fentanyl,” she told the Akron Beacon Journal. “If your kid doesn’t know and they smoke pot or God forbid [something else], they need to be aware that could kill them. Even just a little bit.”

Autopsies have been completed. However, the medical examiner’s toxicology reports are expected to take a few more weeks.

“I am thankful that the last thing I said to my daughter is ‘I love you,’’’ Andrade’s mother told the Beacon Journal. “This should not happen to any parent.”
