Boulder Police had initially warned of “possibly tainted” cocaine after several college students who were “sick/overdosing” were transported to the hospital from the Kappa Sigma fraternity at CU Boulder. Police now believe they had consumed an “extreme amount of alcohol and some had consumed drugs,” according to a Dec. 10 release. Investigations are ongoing as to whether the incident was related to pledging at the fraternity, according to city releases. All rides are free through Jan. 9, and will cost $2 after that, with rides for students, seniors and those with disabilities for $1 per trip. • The City of Boulder is seeking feedback on street safety improvements for Folsom Street between Pine Street and Colorado Avenue.
