Spike in heroin deaths investigated by police

GAITHERSBURG, Md. (AP) - Montgomery County police say as many people have died from heroin overdoses in the last few months as in the previous three years combined.

Police say they're investigating the spike in overdose deaths, which they call alarming.

They say at least seven deaths attributable to heroin have occurred since March, and six of those seven have happened since the beginning of June.
