Police in Freiburg confirmed on Friday that Carolin Gruber, 27, whose body had been found in a forest to the northwest of the city on Thursday, had been raped and then murdered.
Less than a month earlier on October 16th, a 19-year-old woman's body was found in the Dreisam river in Freiburg. The student was on her way home from a party on her bike when she was attacked.
A post mortem also revealed that she had been raped before her death.
Police are not sure whether she was drowned by her attacker or whether she fell into the river and drowned thereafter.
Investigators are now looking into whether the two cases are related to each other. There is as yet no concrete evidence to suggest that the same man attacked the two women.
