A woman died after she was attacked by her fiance’s dog in Southern Maryland, officials said, and law enforcement shot and killed the animal.

The incident unfolded around 7:15 a.m. Thursday along Cherry Hill Road near Route 4 in Huntingtown, according to Maryland State Police. A trooper went to the area in response to calls from drivers about an animal.

When the trooper arrived, he found the dog “actively engaged in the attack in an overgrown area” near the highway. The dog, a Dogo Argentino breed, attacked 28-year-old Jenna Rae Sutphin.

As the trooper got closer, the dog started to move aggressively toward him. The trooper shot the dog with his department-issued service weapon, and the dog ran after it was hit.

The trooper helped Sutphin until emergency personnel arrived. She was taken to a hospital and then airlifted to MedStar Washington Hospital Center. She died there around 5 p.m. Thursday, according to state police officials.

Following the attack, authorities said they found the dog not far from the area. In a statement, officials said, “In an attempt to apprehend the dog and prevent it from doing further harm to anyone, police on scene fired again, fatally wounding the animal.”

Maryland State Police said the case remains under investigation and that no charges have been filed. Officials said they do not yet know what prompted the dog to attack the victim.
