Investigators searching through his phone found hundreds of texts from his girlfriend of 18 months, allegedly telling him to "go kill himself" or "go die", or that everyone would be better off without him.
Prosecutors claim You, who is from South Korea, was "physically, verbally and psychologically abusive", and had "complete and total control over Mr. Urtula both mentally and emotionally."
They claim she knowingly isolated Urtula from friends and family, while being fully aware of the depression and suicidal thoughts brought on by her alleged abuse.
Suffolk District Attorney Rachael Rollins compared the case to that of Michelle Carter, who was infamously convicted of the involuntary manslaughter of Conrad Roy III after she was deemed to have persuaded him to kill himself in 2014.
"But where I would distinguish, and I think the facts will show in Carter there was very limited physical contact prior and some very egregious language in the instance or moments leading up to the death. We have quite frankly, I would say the opposite of that," Rollins said.
"We have a barrage of a complete and utter attack on this man's very will and conscience and psyche by an individual to the tune of 47,000 text messages in the two months leading up."
You is currently in South Korea; prosecutors are trying to convince her lawyers to have her return voluntarily. If she refuses, Rollins will attempt to have her extradited.
