Two elderly sisters from Monroe County, Pennsylvania were arrested for allegedly distributing drugs after being arrested on April 14.

Elizabeth Marie Grube, 70, and her 65-year-old sister, Elaine Volkert, are facing drug charges after investigators seized 400 bags of heroin worth more than $8,000 and more than $2,000 in cash from Grube's home.

Police also seized 988 bags of heroin with a street value of $20,000 and approximately $1,600 in cash from Volkert's home, also on the 1000 block of Ehler Street. In addition, police confiscated quantities of Oxycontin and marijuana during the search.

Grube and Volkert had been selling between 500 and 1,500 bags of heroin every two weeks for the past two months, according to investigators. Prior to selling heroin, the sisters had been selling crack cocaine and have been charged with possession with the intent to deliver a controlled substance and criminal conspiracy. Their bail was set at $20,000.
