The deceased was identified as a Mae Hong Son resident who came to study in a university in Chiang Mai. Her body was sent to Maharaj Nakorn Chiang Mai Hospital.
Police said that she hanged herself with an electric cable in a balcony whose window was covered with a blanket. Police said there was no evidence of physical assault on her body.
Her friends who reported the incident to police said she had become aloof for a month. When they found the light in the room had not been turned off, they contacted her boyfriend trying to open the door.
She reportedly became stressed after her father had a serious illness while she found out that she was pregnant, and police suspected that the stress might have driven her to commit suicide.
