A 20-year-old girl is facing 20 years in prison if convicted of involuntary manslaughter in the death of her 18-year-old boyfriend, 3 years ago.
Michelle Carter was charged in 2014 with the death of Conrad Roy III who was found dead in his pickup truck after suffering carbon monoxide poisoning.
Prosecutors said the then 17-year-old teen had persuaded Conrad to kill himself as a bid for attention as the grieving girlfriend.
"She used Conrad as a pawn in her sick game of life and death," said prosecutor Maryclare Flynn.
Michelle and Conrad met while on vacation in Florida several years earlier, while she referred to herself as his girlfriend, his family and friends said they never knew of the relationship. The couple communicated mainly through text and emails because they lived 50 miles apart, and had not seen each other in nearly a year.
