MOSCOW (AP) — Russian investigators say the body of an American student has been found on the outskirts of a Siberian village, a week after he vanished from a guesthouse in the middle of the night.

A statement from the Investigative Committee said Colin Madsen's body was found Monday about 1.5 kilometers (a mile) outside Arshan, a resort village poplar for its mineral springs and proximity to mountains.

The statement said there were no visible injuries to the 25-year-old Madsen and that his documents and money had been left untouched.

Madsen, who was a student at a university in Irkutsk, came to Arshan on March 26 with friends who intended to hike to a mountain summit. But he left the guesthouse between 2 and 5 a.m., without a coat despite freezing temperatures.
