He was pulling out of the Heydrich family driveway and was making a right to go down the road on his bike. I guess a truck carrying the local football team came up behind him and accidentally clipped him. I'm not sure but I think he died instantly. So very sad...what an adorable little boy. All of the Heydrich kids are cute!
Heider was with Klaus at the time of the accident. Sadly, Klaus died later that day from his injuries. This is a reason why I feel sorrow for Lina. Firstly she's got three children and heavily pregnant with her fourth and loses her husband - a tradgedy for her. Then she gives birth to second daughter and fourth child Marte just over a month later. Then a few months after that, loses her oldest son. I've seen very few pictures of Silke Heydrich, but she apparently looks a great deal like her father.
I wish I knew ! I've always wondered about that, or if he was alone while riding the bike. Or if his poor Mom saw it happen from the house or yard. The Heydrich family has certainly had their share of continuing tragedy. Reinhard's brother committed suicide in 1944 and his Mom (the stern disciplinarian) died of starvation in eastern Germany in 1946.
