GRAND RAPIDS, Mich. (WOOD) — In the 1990s, more than a dozen women were found dead in the Grand Rapids area.

More than two decades later, a man has been arrested in the death of one of those women: Garry Dean Artman faces multiple charges in the death of Sharon Kay Hammack.

Artman, a 64-year-old trucker from Columbia County, Florida, was arrested in Mississippi following a traffic stop while driving a commercial vehicle. He faces charges of open murder, felony murder and criminal sexual conduct first degree in the death of Hammack.

He is also suspected in the murder of a woman in Maryland.

In a Monday morning press conference, Kent County Sheriff Michelle LaJoye-Young said that since the 1990s, there have been various task forces that try to solve cold cases.

“We try to remember the pain that family suffers when there’s a loss such as this. We remember the person whose life is cut short and the impact that they still had… That’s why we continue to still work on cold cases to the best of our ability throughout all these years,” LaJoye-Young said.

Kent County Prosecutor Chris Becker added that “…every time we do get a solved case, a match like this, it does help proceed investigations locally and potentially statewide or nationally.”

“…It gives hope, I think it, to other families and other victims who are going through some of what you’ve gone through for the last 20 years, and I can’t imagine that and I’m so grateful that you’re here and that we could do something for you,” Becker said to family members of Hammack who attended the press conference.

Hammack, a 29-year-old mother of two with a third on the way, according to family members, was killed in 1996 when detectives say Artman raped, strangled, stabbed and hogtied her. She was dumped on the side of 76th Street near Kraft Avenue in Caledonia Township.

Her body was found the same day she was murdered, giving detectives leads on who her killer could be.

Joel Schultze, forensic DNA supervisor with the Michigan State Police, said during the news conference that MSP “prepped a sample and sent that out to Identifinders, which is the same company that we used for the 1987 homicide out of Niles.”

DNA from the crime scene led investigators to Artman.

But the bodies of many of the other women killed in the 1990s were not discovered immediately — only skeletal remains were left by the time some of the women were found — and arrests have not been made in those cases.

Most of the victims struggled with substance abuse and engaged in commercial sexual activity, though Tara Aday with Safe Haven Ministries said it can be difficult to discern the difference between commercial sexual activity and sex trafficking.

She said if an adult is doing commercial sexual activity as a result of force, fraud or coercion, then they are being trafficked. The differences between the two can be nearly invisible, making it difficult to tell whether someone taking part in the sale of sex is experiencing exploitation or trafficking. 

A task force was formed in 1996 to investigate the string of murders, but investigators never reached any conclusions.

News 8 obtained death records of the 12 women who were killed around the same time Hammack was:

LESA IRENE OTBERG
