I was rear-ended by a BMW suv type car that witnesses reported traveling 100 mph or more on eastbound I-80 right after 42nd street at 1:30 A.M. 8/6/2015 while on my way to pick my wife up from work. Witnesses think that the car continued on to I-480 north but could have went I-80 as well. They should have extensive damage on the front end as they hit me while I was going 50 mph in a construction zone and they were traveling 100 mph or more. Judging by the extensive damage on my bumper the BMW should have more damage on the passenger side of their front-end as it appears they may have tried turning left before they hit me. It is a darker colored SUV, possibly grey or black and it should have white paint transfer marks from my car where they struck me. $500 for information that leads to an arrest.
