The Milwaukee Journal-Sentinel said this:
A motorcyclist killed last night on northbound I-43 has been identified as James E. Jewell of Milwaukee, the Milwaukee County medical examiner's office said this morning.
Jewell, 44, was pronounced dead at the scene, near I-43 and W. Mineral St.
The crash was reported about 8 p.m. Jewell entered the freeway at W. Becher St., lost control of the motorcycle and struck a center median, according to the Milwaukee County Sheriff's Department.
That certainly doesn't answer my questions, but maybe there will be more in the paper later. I was glad to see that no one else caused the crash.
Okay...lots of work to do, so I better get back to it.
