IONIA COUNTY, MI -- Family members of Dave and Lisa Somers are in shock Monday after a weekend shooting left the two of them dead.

They died in an apparent murder-suicide on I-96, at a location about 10 miles southeast of Lowell. Lisa Somers' 18-year-old daughter, Amedy Dewey, was hospitalized following the incident.

Police haven't released many details as to a motive or what led up to the Saturday evening shootings on I-96, though they are calling the incident an apparent murder and suicide.

"The entire family is in shock," said Cherie Hall, one of Dave Somers' cousins. "Dave was the kindest person on the face of the earth. This tragic occurrence is not the person everyone knew as my cousin Dave."

Shelbi Somers, 23, said her father planned to pick up her step-mother and step-sister from the airport Saturday after they returned from a trip to the Bahamas.

She hadn't heard any additional details from police as of Monday morning regarding what led up to the shooting.

Ionia County Sheriff's deputies located the bodies of Dave and Lisa Somers around 10 p.m. Saturday, Jan. 6, on the shoulder of I-96 near Nash Highway. The two adults died of apparent gunshot wounds, and a loaded shotgun was found under Dave's body, police said.

Inside the couple's silver Chevrolet Equinox, police located Amedy Dewey, who had also been shot. She was transported to Spectrum Health Butterworth Hospital, where she was listed in stable but critical condition on Sunday.

Hospital personnel declined to provide an update for Dewey's condition Monday morning. She is a high school senior in the Midland area.

Shelbi Somers said Dave and Lisa were both outgoing people who shared a fandom of the Detroit Tigers and an appreciation of softball. The couple met through an adult softball team in Manistee County, and they were married in 2013.

"They were just really well-known people, good people," Shelbi Somers said. "My dad was a fun guy who would help anyone who needed help. Everyone knew who he was and liked him. He was a really good dad."

Dave Somers, 51, was a Twin Lake native and graduate of Reeths-Puffer High School. He was an avid baseball and softball fan, and enjoyed hunting.

Lisa Somers, 51, grew up in Ludington and graduated from Ludington High School and Ferris State University. She worked at Avon Automotive as an assistant to the general manager, and she taught courses at West Shore Community College.

In addition to Amedy, Lisa Somers was the mother to two adult sons -- Adam and Dillon Helminiak. Neither were Dave Somers' biological children.

As news of the couples' deaths spread, friends and family members took to social media to voice their surprise and offer their condolences.

"They will be very missed," reads one post. "Both amazing great people and I don't think it will ever make sense..... Spent much time with them both had many a beers and many a laughs."

A friend and softball teammate of Dave and Lisa's created a GoFundMe page to raise money to assist with Amedy's medical bills as well as funeral expenses for Lisa Somers.
