CASTLE ROCK, Colo. -- Investigators said Wednesday that a laboratory found no heroin in marijuana confiscated from high school students, contradicting field tests done immediately after the arrests last month.
Four students were arrested in two incidents near Mountain Vista High School. Douglas County deputies said at the time their field tests showed marijuana taken from the students was laced with the harder drug.
Lab tests done by the Colorado Bureau of Investigation at the request of the sheriff's department found no heroin, sheriff's Lt. Alan Stanton said.
