Police are reportedly investigating whether an Afghan migrant who confessed to the rape and murder of the daughter of a high-ranking EU official in Freiburg, in Germany, also killed another woman, the U.K’s Express reported.
The body of 27-year-old Carolin Gruber was found in woodland north of the city on November 10.
She had been missing for four days after going out for a run and failing to return home.
Less than a month earlier, Maria Ladenburger, 19, was found dead in the city’s River Dreisam.
She had been returning home from a party when she was assaulted on a cycle path. She too had been raped before apparently being drowned.
On Friday, Frieburg police announced they had arrested a 17-year-old migrant from Afghanistan on suspicion of murdering Ladenburger, the newspaper reported.
The suspect was caught after police found DNA on a scarf belonging to the victim close to the murder scene.
Following his arrest the teenage migrant pleaded guilty to the attack and will be sentenced next year.
Detectives are now investigating whether the two killings are connected, although as yet there is no evidence to suggest the same man killed both women.
The suspect reportedly arrived in Germany last year as an unaccompanied minor and lived with a local family in the city.
