Minnesota Man Accused of Leaving Fiancée for Dead After Argument and DUI Incident

A Minnesota man is facing serious charges after allegedly driving drunk and abandoning his injured fiancée following a heated argument that ended with her jumping out of his moving vehicle.

Authorities say the man, Johnathan James Schafer, never called 911 and instead spent more than 40 minutes on the phone with his mother and a friend before police were alerted.

What Happened

On the night of May 15, 2025, 35-year-old Schafer allegedly drove around with his fiancée, 23-year-old Julia Marie Marthaler, after they visited a bar for dinner and drinks.

An argument ensued, during which Marthaler reportedly jumped out of the moving truck. Schafer did not call emergency services. Instead, he contacted his mother and a friend.

Both women ultimately called 911 themselves, relaying Schafer’s claim that Marthaler had leapt from his truck near a cemetery in Becker, Minnesota.

Key Details

  • Schafer was reportedly intoxicated during the incident.
  • Authorities found him in a dog park parking lot, still on the phone and smelling of alcohol.
  • Blood was discovered on the truck door and Schafer’s hand. A shotgun was also located in the vehicle.
  • Schafer led police to Marthaler’s location, where she was found critically injured with severe head trauma. She was pronounced dead at the scene.
  • Schafer never contacted 911 during the 42-minute window before his mother and friend alerted authorities.
