Court documents state Nguyen, her mother and her mother’s boyfriend drove to the trailer park on Ames Boulevard to speak with Thach’s father after Thach sent Nguyen “derogatory” text messages.

The documents state, “Thach entered the room and slapped Nguyen as she sat on the sofa” after her mother spoke with Thach’s father.

Connick said Nguyen’s mother called 911 after Thac locked the door, told Nguyen she couldn’t leave and threatened to kill her.

Nguyen was then fatally stabbed.
