Vapor cloud makes senior citizens sick
COMMERCE CITY — Authorities are trying to locate the source of a mysterious vapor cloud that made a group of senior citizens sick.
The group was about to board a bus at a recreation center on Sunday to go listen to children sing Christmas carols when they started choking.
Commerce City police commander Dennis Moon tells KUSA-TV the vapor cloud was gone by the time emergence teams arrived.
No serious injuries were reported, but some people still felt sick on Monday.
