IONIA COUNTY, MI -- Police say it's not clear what caused an apparent murder-suicide on the side of I-96 in Boston Township Saturday night.

According to a release from the Ionia County Sheriff's Office, 51-year-old David Somers and 51-year-old Lisa Somers were found dead from gunshot wounds after 10 p.m. on Jan. 6. A loaded shotgun was found underneath David's body on the roadway's shoulder, police said.

Police did not specifically say if David was the shooter.

Deputies were called to the scene at approximately 9:39 p.m. to I-96 near Nash Hwy in Boston Township.

A responding deputy discovered a silver Chevrolet Equinox parked on the roadway with the lift gate and passenger side doors opened. A third victim was found inside the vehicle, injured by an apparent gunshot wound.

Amedy Dewey, Lisa's 18-year-old daughter, was treated at the scene until other officers and first responders arrived. She was transported to Spectrum Butterworth Hospital in Grand Rapids and is listed in critical condition.

Police said Dewey is stable Sunday, but her condition is still critical.

Further investigation at the scene determined that this was a case of an apparent murder and suicide.

All three involved in the shooting are from Kaleva.

Police said there is no clear motive what prompted the homicide, and detectives will continue to investigate the case.

The Michigan State Police Lakeview Post assisted at the scene, and also helped close a portion of eastbound I-96 near mile marker 59 as detectives investigated this shooting and collected evidence.

The highway reopened at 1:40 a.m. Sunday morning.
