The death of the mother of New Orleans Saints quarterback Drew Brees has been ruled a suicide.

Mina Brees, an attorney from Austin, Texas, died Aug. 7 while visiting Colorado. Grand County coroner Brenda Bock concluded this week that the 59-year-old Brees died of a prescription drug overdose and ruled the death a suicide.

Bock said Brees died while staying at the home of a friend in Granby near Rocky Mountain National Park.

It took longer than three months for autopsy results to be released, but Bock said that’s typical for cases involving toxicology tests.

The Austin American Statesman reported that three days before Brees died, the Texas attorney general’s office subpoenaed her business records.
