Niels Hogel was born in Wilhelmshaven on December 30, 1976, into a family of nurses, and qualified in 1997. He worked in the cardiac surgery intensive care unit at the Oldenburg clinic from 1999 to 2002, and at the Delmenhorst clinic from 2003 to 2005. German reporting called him the Angel of Death.
He injected patients with drugs including ajmaline, sotalol, lidocaine, amiodarone and calcium chloride, which cause cardiac arrest or catastrophic circulatory collapse, and then took part in the resuscitation. He told the court he had done it out of boredom, for the thrill of the emergency and to be admired for saving them, and that he had felt euphoric when it worked and wretched when it did not.
The number is what makes this case what it is. He was convicted in 2008 of one attempted murder, after being caught with a syringe. He was convicted in 2015 of two murders and two attempted murders. Only then did a serious investigation begin, and it required the exhumation of well over a hundred bodies from cemeteries across Germany, Poland and Turkey. In June 2019 he was convicted of eighty-five further murders and given a life sentence with a finding of particular gravity of guilt, which in practice removes any prospect of release.
The commission that examined the case concluded that the real total is unknowable and probably exceeds three hundred, and that it cannot be established because a great many of the possible victims were cremated.
He was also not stopped when he could have been. Both clinics had noticed the death rate on his shifts and the missing drugs. Oldenburg moved him on with a neutral reference in 2002 rather than reporting him. Delmenhorst delayed for weeks after suspicion crystallised. Seven former colleagues and managers at the two hospitals were subsequently prosecuted, and several were convicted, for failing to act.
