A Gaithersburg man has been convicted of killing his 12-year-old stepdaughter Jessica Nguyen.
During a week-long trial in Montgomery County, prosecutors presented evidence that David Hang killed the little girl to get out of his marriage to her mother, Kim Vu. Investigators say Hang married Vu so she could get U.S. citizenship.
When he met another woman and wanted to get out of the marriage, Vu and her relatives said no and that is when the trouble started.
"The family would not let him out of the marriage as soon as he wanted. He let it be known he would get revenge," Montgomery County State's Attorney John McCarthy says.
Investigators say Hang exacted his revenge on pint-sized Nguyen, stabbing her 43 times with a machete. A knife case with his DNA on it was found beside her tiny body.
"This was clearly premeditated," McCarthy says. "We'll be seeking a sentence of life without parole. We think he should die in prison for this crime."
Courtroom observers were outraged at Hang's demeanor during some of the trial, saying he was smirking and smiling. That all changed when the jury came back with its guilty verdict.
"Today, he was not laughing and justice has been served for Jessica's family and the community," says prosecutor Stephen Chaikin.
Nguyen's family says the verdict is what they waited a year for.
"Even though it won't bring Jessica back to us, we are grateful to know David Hang will never get out of prison, and he can't hurt the community," Hoa Dinh says.
