Following his arrest the suspect, aged 17, pleaded guilty to the attack and will be sentenced next year.
However, prosecutors say he can still change his plea and it’s unknown if he has admitted raping Maria.
The unnamed migrant arrived in Germany last year as an unaccompanied minor and lived with a local family in the city.
Ms Ladenburger reportedly worked in her spare time helping out in refugee homes in Freiburg.
But it is unclear whether she ever met her murderer before he took her life.
The dead girl’s father is Dr. Clemens Ladenburger, a lawyer who works as the right hand man to the legal director of the European Commission.
A funeral requiem was held for Maria on October in Notre Dame des Graces Church in Brussels.
On December 6 this year Maria would have been 20.
David Müller, head of the police’s Special Commission, said: “Through intervie
ws and a web-based survey, we were able to reconstruct Maria’s final hours.
“The 19-year-old student had been at a party. By 2.37am, she left the party. Maria then cycled home, as usual. The young woman had been the victim of a sexual offence and a violent crime.”
The horror killing piles more pressure on Chancellor Angela Merkel who opened the nation’s borders to more than one million migrants since 2015.
Earlier this week she was blasted by a father-of-four who said he no longer felt safe because of the migrant inlux.
But Dieter Salomon, the mayor of Freiburg warned people not to “apply perpetrator background for sweeping judgements, but to view it as an isolated incident”.
However, police are also investigating whether the murder of Maria is linked to another killing just a month later.
Carolin Gruber was sexually assaulted and murdered in an attack at the same spot.
The 27-year-old was found in woodland elsewhere in the city on Novermber 10.

As part of their findings, which provoked another wave of revulsion against Merkel’s “open door” policies, officials confirmed that the suspect entered Germany illegally and later filed an asylum request as an unaccompanied minor. He then lived with a foster family in Freiburg. He had been charged once before with inflicting bodily harm, but the case was later dropped, police told journalists during the press conference without giving further details. It was unclear if the suspect and the victim had known each other before the incident, or if the attack was planned in advance.
If politicians – and those who approve of open borders – were personally required to house, feed and cloth Muslim refugees and illegal aliens until they were entirely self-sufficient we would not have an immigration problem in America.
