Police in southern Vietnam on Saturday said medical examiners have found signs of rape on the bodies of two schoolgirls discovered in a stream on Thursday afternoon.
A lot of blood was also found inside their mouths, police added.
The two victims, both seventh-graders in Binh Phuoc Province, reportedly joined a group of friends for a camping trip near the stream on Wednesday.
The 12-year-old girls, who went to the campsite together on one bicycle, did not return home in the evening.
Their family members went searching for them and discovered their bodies lying face down at the bottom of the stream, which is one meter deep.
Further investigations are ongoing.
