After the assassin in Halle took two prison guards hostage, the Saxony-Anhalt public prosecutor's office took over the investigation.
The head of the Burg prison, Ulrike Hagemann, praised the behavior of the prison staff in a briefing to the state parliament on Wednesday.
In particular, one of the two hostages behaved skillfully.
The man used an inattentiveness of the 30-year-old assassin Stephan Balliet to jerkily free himself from him, which allowed his colleagues to gain access.
Balliet had threatened a guard with a home-made device while locking his cell and forced him to open doors for him.
Balliet later traded his first hostage for another guard.
An internal police report speaks of a "weapon-like object" and a "shot" by Balliet at a fence.
Judicial circles pointed out that the hostages feared for their lives, but that the matter was difficult to interpret.
A first meeting of the Legal Committee on Wednesday afternoon brought little new knowledge.
The crime did make a "gunshot-like noise," said prison warden Hagemann.
But she "cannot say what it is, what it consisted of and what danger it poses".
Balliet's search also found craft scissors, a knife and a can opener.
The Legal Committee meeting was scheduled to continue in the evening.
The deputies also want to pursue the question of whether Balliet had helpers among fellow inmates, employees or outside the prison.
The prison warden stated that the staff was not aware of any right-wing extremist tendencies and that Balliet had no right-wing extremist fellow prisoners in his department.
On October 9, 2019, Balliet entered the Halle synagogue and wanted to massacre there with a self-made gun.
When he failed, he shot two people outside the church.
The right-wing extremist was therefore sentenced to life imprisonment with subsequent preventive detention.
