 Authorities say no other vehicles were involved since Friday. There have been 10 road deaths across the state. Law enforcement officials say it is not normal to have so many crashes in such a short amount of time. Meanwhile, a motorcyclist is dead after crashing into the back of a pickup truck in Alton Sunday evening. 25-year-old Colin Zaremba of Belmont struck a truck driven by a 75-year-old woman from Alton around 6.15 in the evening Sunday.
