ROLLAND TWP, MI -- A 68-year-old man told a 911 dispatcher he shot his wife and indicated she was still alive, then he killed himself, police officials say. The dispatcher heard a gunshot over the phone and then the line went dead.

The call was made just after 5 p.m. Wednesday, March 14, said Isabella County Sheriff Mike Main. Within minutes, members of a law enforcement tactical team approached the couple's home at 10803 Brinton Road.

Through a window, they saw Brad Hatt dead from a suspected self-inflicted gunshot wound, Main said. They entered the residence and found his wife, 66-year-old Janice Hatt, shot multiple times but still alive in a bedroom, the sheriff said.

Janice Hatt was airlifted from the shooting scene to a Grand Rapids-area hospital. Main said she was last listed in critical condition and was under an induced coma.

"What we're getting was it's pretty touch and go," for Janice Hatt, he said.

The Hatts lived by themselves at their residence in southwestern Isabella County. Nothing there, so far, has pointed investigators to a motive, Main said.

"We're kind of at a blank here," the sheriff said.

The next steps, Main said, is to interview family and friends and analyze the couple's computers and phones to determine what might have sparked the violent acts.

"I think whatever happened transpired pretty quickly," he said.

Main said the suspected weapon was a semi-automatic handgun. Neither Hatt has a criminal history, and police have never responded to the home for domestic issues, the sheriff said.

The Hatt residence is listed online as the location of The Gardens at Rocky Meadows. The business bills itself as an 80-acre estate available for wedding and party rentals, according to the website.

The Michigan State Police Crime Lab was aided the sheriff's office in collecting and analyzing evidence from the scene.
