A short email from his sister-in-law Sabrina Booth:

“On Thursday, July 14th, my brother-in-law and drummer for the band Silkworm, Michael Dahlquist, was killed in Chicago. Two of his friends that were also in bands were killed as well, Doug and John. His immediate family is currently in Chicago attending to the necessary arrangements. At this time, it is very difficult for us to personally write and submit any type of official announcement or obituary for him, but we would like his death to be mentioned so as to inform his many friends and other people whose lives he touched in the Seattle area. He was from Seattle and lived here for many years. We are hoping to have a memorial service for him at the end of the month when his mother and brothers have returned from Chicago.

The Chicago News Tribune has stories about the collision online.

Photos and other information are on the message board at Silkworm.net

I believe that Steve Albini, who is a friend and worked with him musically, has written a memoriam for him….at electrical.com, the site for the recording studio Electrical Audio in Chicago.”
