German police found two adults and three children shot or stabbed to death in a family home in a town south of Berlin, they said on Saturday.
They were called to the house in a suburb of the town of Koenigs Wusterhausen after being alerted by witnesses who had seen lifeless bodies in the house, according to a statement from police and prosecutors.
They found two adults, both 40, and children aged four, eight and 10, dead from gunshot and stab wounds. Police said they had opened a murder investigation but gave no further details.
German media reported that all five had been in quarantine due to COVID-19.
