The Cuyahoga County Medical Examiner is investigating as many as six possible overdose deaths from this weekend.

The cases are all under investigation. Tests are being conducted to determine the cause of death.

The medical examiner says individuals using drugs and their friends and family should be aware of the increased number of fatalities, in light of the ongoing heroin epidemic in the county. They should also watch for excessive sleepiness and breathing problems and seek emergency intervention as soon as possible.
