Rochester N.Y- Opening statements begin Thursday in the double trial of two people charged with killing a Fairport teacher.
Megan Merkel and Mark Scerbo are charged with vehicular manslaughter and DWI .
Authorities say Scerbo was riding a motorcycle last July when he hit Heather Boyum as she rode her bicycle on Route 250 in Penfield. The impact forced her into the path of Merkel's car.
Merkel and Scerbo will be tried at the same time, but with different juries.
