TANGIPAHOA PARISH - A domestic incident that occurred outside of an elementary school Thursday morning has prompted law enforcement to take security measures.

According to the Tanigpahoa Parish Sheriff's Office, deputies responded to Martha Vinyard Elementary School in Ponchatoula after a threat was made against an employee. Officials say 39-year-old Chad Milton showed up at his wife's workplace Thursday morning demanding to speak with her, despite having a protective order against him. She refused to speak with him and he soon left the school, ramming into her parked car on his way out, police said.

Milton fled the scene and began sending threatening text messages to the victim. Screenshots of the messages obtained by WWL show that Milton sent the woman texts demanding she call him along with a picture of a rifle.
