News search engines; transit and traffic too

Last night I decided to avoid Red Line delays by taking route 147 north instead.  Everything was pretty fine until we approached Loyola.  All traffic was diverted in both directions.  Cars were going west (to where?).  Buses were just sitting there.  Although there seems to be plenty of room to u-turn and reroute to Clark Street, apparently cta wasn’t able to do this. Or maybe Clark was too congested.

I got off the stopped bus, walked up to the blockage, the entire street was closed off with yellow tape, tho sidewalks were open.  No indication of what happened, so I went upstairs to the red line (which was performing its own delays, but restored service after a few minutes).  So why was the street blocked?

This afternoon I used news.google and news.yahoo to answer that question.  Searching for “sheridan” and “loyola”, google was unable to come up with anything relevant, while yahoo linked to four articles (well, actually four copies of two articles) which explained that pedestrian had been killed crossing the street.   (Even googling for the name of the victim yielded nothing.) Which doesn’t explain why buses could not have been allowed thru while the investigation was conducted.
