I don't have a scanner and, as usual with Denver, nothing was in the news. Friday night, about 7:15 PM, an unmarked car with lights and siren went flying up Federal at nearly double the speed limit, followed minutes later by at least 8 patrol cars, then a few minutes later by 5 more patrol cars. Big hurry, lights and sirens, no fire trucks or ambulance. Looked like they all turned East on 38th. Was wondering if anyone knew what was up with that? Thanks.
