The Arizona Department of Public Safety (Highway Patrol) is looking for a White semi truck pulling a white box trailer that was invovled in a serious injury hit and run collision on I-10 at milepost 229 near Marana on the evening of 1/12/21 at approximately 2200 hours.  The truck struck two tow truck operators on the side of the road that were loading up a vehicle and fled the scene.  The semi truck should have contact damage to the front right and right side.  The headlights possibly have a blue tint to them and the passenger headlight may be out.  The semi struck the tow truk as well so there should be obvious damage.
