Allegan County Sheriff’s deputies were dispatched to a Dorr Township residence around 4 a.m. Wednesday on a call of a domestic violence situation involving family members that escalated to a shooting and an apparent suicide.

As an active investigation, all the details are not yet available for release. Details could change as all the evidence is collected and the Medical Examiner’s Office completes their portion of the investigation, an Allegan County Sheriff’s Office news release said.

The initial investigation and interviews indicate there was a domestic violence argument between brothers in their 20’s, and a step-father in his mid 40’s, officials said.

The argument escalated when one of the brothers went to an separate upstairs residence and got a rifle.

He returned to the downstairs residence and shot the stepfather, causing a non-life threatening injury, then turned the weapon on himself. According to the witnesses and the initial scene investigation, the suspect died as the result of a self-inflicted gunshot wound. Deputies and investigators are still interviewing witnesses and processing the scene for evidence.
