Tokyo CNN  — 

Police in Japan are trying to identify the body of an elderly woman found stuffed in a bright yellow suitcase at a Tokyo train station.

The discovery was made by an employee of the coin-operated locker service at JR Tokyo Station in the city’s Chiyoda Ward.

“There was an abnormal odor and he saw hair,” said Chiemi Sugimoto, a spokesman for JR Tokyo Retail Net, which operates the lockers.

The employee opened the suitcase on Sunday, May 31– more than one month after staff noticed it hadn’t been claimed and put it into storage, Sugimoto said.

The woman appeared to be between 70 and 90-years-old and had no obvious external signs of injury, according the Japan Times, citing the Marunouchi Police Station.

Her body was curled up in the bag, which was 70 cm high, 50 cm wide and 25 cm thick (approximately 27 by 20, by 10 inches), the report said.

JR Tokyo station is one of busiest stations in Japan, with more than 3,000 trains passing through it daily.

It serves Shinkansen high-speed rail lines and many of Japan Railway’s regional commuter lines, as well as the Tokyo Metro network.
