Megan Merkel is heading back to prison -- this time for having drugs in jail.
She was sentenced yesterday to 3-and-one-half to 7 years in prison.
Merkel previously served ten months for drunken driving in the 2012 crash that killed bicyclist Heather Boyum in Penfield.
Merkel hit Boyum with her car after a man hit Boyum with his motorcycle. Merkel pleaded guilty this year after she was caught with heroin at the Monroe County jail last December.
