One of the three Saline teenagers charged with the murder of a Michigan State University student will take his chances at a September trial.
Samantha Grigg testified that her friend, Brendan Heim, beat 19-year-old Dustyn Frolka with a pair of brass knuckles as they drove along Interstate 69, outside of East Lansing.
Samantha Grigg is expected to serve up to 7 years in prison as part of a deal with prosecutors.
Police say Dustyn Frolka was beaten with brass knuckles during a robbery and then thrown from a moving vehicle.
Dustyn Frolka was rushed Saturday night to Sparrow Hospital in Lansing where he was pronounced dead.
