The mother of the boy who shot his 15-year-old cousin in his bedroom in Amersfoort last April, was on trial this morning. In court, she said she never heard a gun go off, even though she was at home. She is charged with gross negligence and wrongful death, because, according to the Public Prosecution Service, she did know that her nephew had been hit by a bullet. She kept silent about this to the rushed emergency services.
