Port Huron Father Pleads Guilty to Killing 17-Year-Old Son and Shooting Two Other Children

The plea, in which the defendant admitted planning the attack and cited stress over a 2020 court case, sets a June 29 sentencing that could impose life terms.

Overview

  • On May 27, 2026, Jeffrey Smerer pleaded guilty to one count of open murder, two counts of assault with intent to murder, two counts of first-degree child abuse, and five felony firearm counts.
  • The shootings occurred in the early morning of Sept. 11, 2025, when Smerer shot his 17-year-old son, who later died, and shot his 13-year-old son and 12-year-old daughter, who were critically wounded.
  • Family members including the children’s mother and an adult son physically restrained Smerer and a subsequent suicide attempt failed after his handgun reportedly jammed and was disarmed.
  • Prosecutors say the surviving children suffered severe, long-term injuries including facial fractures and paralysis from the neck down that required reconstructive surgery and extended care.
  • Smerer faces life sentences on the most serious counts plus consecutive penalties for the firearm convictions and his statements about planning and stress have focused attention on gun access, mental-health support, and victim services in the community.
