The 22-year-old daughter of Minnesota GOP gubernatorial candidate Jeff Johnson was allegedly fatally injured by her husband Saturday in what police said was an apparent domestic incident.

Officers with the St. Cloud Police Department responded to a residence in the 3100 block of 40 Ave. S. around 8:20 p.m. Saturday for a “medical emergency.”

Officers located a 22-year-old female – later identified as Hallie Marie Tobler – with “multiple injuries.”

A 23-year-old male – later identified as Dylan Michael Tobler – was also found at the scene with what investigators believe were self-inflicted injuries.

Hallie Tobler was transported to the Midwest Medical Examiner’s Office for a medical examination. Dylan was transported to St. Cloud Hospital and is in “stable condition,” police said. He is now in the custody of the St. Cloud Police Department and will be transferred to the Stearns County Jail where he will be held on charges related to the incident.

The Minnesota Republican Party said it was “heartbroken” by Saturday night’s tragic incident.

“There are no words that can adequately express the sorrow we feel for Jeff and his family,” the Minnesota Republican Party said in a statement. “The passing of a child is unimaginable, and our thoughts and prayers are with them as they grieve this devastating tragedy.”

Johnson’s campaign page appeared to have been taken down by Tuesday morning.

The Minnesota Republican Party said Jeff has suspended his campaign out of “respect for his family and the enormity of this passing.”
