AKIPRESS.COM - A suitcase abandoned more than a month ago at Japan’s Tokyo Station was found over the weekend with an elderly woman’s body zipped up inside it, according to police.

The bright yellow suitcase had been sitting in a coin locker near the station’s Marunouchi South Exit since April 26, the Japan Times reported. Since no one had come forward to claim it, a worker at Tokyo’s main train station opened it on Sunday — and discovered the decomposing body. “There was an abnormal odor when we opened the suitcase,” a spokesman told reporters, according to Agence France-Presse. “Then we saw hair.”

The body was wrapped in a blanket and stuffed in the bag. Police said the body appears to be a female between age 70 and 90, measuring about 4-feet, 7-inches tall. It showed no signs of external wounds, police said.

Police are now working to establish the person’s identity and cause of death as well as examining security footage to try to determine who left the bag, the Japan Times reported.

Stations in Japan provide lockers for commuters to store their belongings and a spokesman said the stations commonly hold unclaimed items for about a month. But Sunday’s discovery no doubt came as a shock.

“We were surprised and horrified,” Junichi Omoto, a spokesman for regional train company East Japan Railway Co., told the Associated Press.
