A jury Thursday found a 42-year-old West Valley City woman guilty of both first-degree felony murder and second-degree felony obstruction of justice.

Thu Huong Thi Nguyen was accused of fatally stabbing the father of her infant child in the midst of a 2013 Labor Day barbecue. A 3rd District Court jury deliberated her fate for six hours, beginning at about 3 p.m., following her three-day trial.

Nguyen will be sentenced May 4 for the Sept. 2, 2013, death of 44-year-old Thai Le.

She faces up to life in prison when she is sentenced by Judge Randall Skanchy.

According to witness testimony at a 2014 preliminary hearing, the couple had been fighting for hours when Nguyen went to the kitchen and got a knife. Le allegedly challenged Nguyen to stab him, and she did, according to that testimony.

But Nguyen, who testified Thursday morning through an interpreter, gave a different account.

"I took the knife in the kitchen and I went to the living room, and I was holding the knife like this," she said, holding out her arm, "and somebody pushed me. Pushed me and grabbed my arm."

She said that she loved Thai, and she felt he loved her, as well.

Le was rushed by car to Pioneer Valley Hospital by people at the party.

Witnesses said at the 2014 preliminary hearing that Nguyen had held her boyfriend up as she said, "The ambulance is too slow; let's take him to the hospital. Help me. I don't want him to die."

A charge of third-degree felony domestic violence in the presence of a child was dismissed by prosecutors at the start of the trial.

The knife used in the stabbing was later found in a kitchen drawer and appeared to have been washed, according to charging documents.

The couple had been together for several years, witnesses at the preliminary hearing said. They were hosting a Labor Day cookout and had been drinking beer with their guests all evening before the stabbing occurred, witnesses said.
