Delta flight attendants found the body of a 61-year-old woman in the restroom of a plane that landed in Atlanta early Wednesday morning, a spokeswoman for the company said.

The crew noticed the restroom was occupied on final approach, spokeswoman Keyra Johnson said. Flight 950 from Los Angeles landed at 5:51 a.m., and Delta officials have not said how long the woman may have been in the restroom.

Atlanta police were notified and met the plane at the gate, Johnson said.

The body was taken to the Georgia Bureau of Investigation Crime Lab in suburban Atlanta for an autopsy later Wednesday, said GBI spokesman John Bankhead. Authorities were awaiting the results to determine the cause of death, Bankhead said.

Authorities have not released the woman’s name.

Atlanta police stationed at Hartsfield-Jackson Atlanta International Airport respond to calls about dead bodies on airplanes a couple of times a year, police spokesman Officer Eric Schwartz said.
