"The motive for the two to plot Sgt. Hassel's death may have been to continue their relationship and reap the Army's death benefit from his murder," prosecutor Mike Sepic said, according to The Associated Press.
Tyrone Hassel's father, Tyron Hassel, Jr. told WSBT he's still in shock over the killing.
“You got to understand, man, this is a person that slept in my home,” Hassel said. “I spent two weeks with this person, after she killed my son.”
“I grieved for her more than I grieved for myself. Because I saw a woman that lost her husband. I look at my grandson and I saw a kid that lost his father,” he said.
Hassel said he felt “deceived” by his daughter-in-law and said if he had one last message for his son, it would be, “I love him.”
