A 27-year-old South Korean woman was found dead early Monday on the bank of a river in Tokyo's Edogawa Ward, police said.

Police examine a site along the Edo River in Tokyo, where a woman's body was found earlier in the morning.

A group of young boys found the body, which is believed to be that of Kwon Un Jong, along the embankment of the Edo River at around 1:10 a.m. and notified police. The case is being investigated as a murder, because Kwon appears to have been strangled, the police said.

Autopsy results showed that Kwon died from suffocation about 12 hours before the body was discovered, the police said.

Kwon, who had no fixed address, was wearing an orange long-sleeved shirt and black shorts, but there were no shoes or personal belongings in the area, indicating she may have been murdered at a different location, according to police.

One of the boys told police there was a towel near the woman's head when they discovered the body.
