After more than 40 years, Ottawa County authorities say they are making progress on solving the murder of Deborah Polinsky.

Polinksy was living in a rented farmhouse on New Holland Street in Port Sheldon at the time of her death. A co-worker found Deborah's body after she didn't show up for her job. She had been stabbed multiple times.

Over the last 18 months, two detectives have been working full time on this case. Now they're hoping to use the power of technology to give the family some closure.

"Her parents are both in their 90s we'd like to get them some answers," Capt. Mark Bennett with the Ottawa County Sheriff's Office said.

This week the Ottawa County Sheriff's office launched 'Justice for Deb Polinsky,' a Facebook page.

"We now know more and more of our investigations center around some type of social media," Capt. Bennett said.

"Even though this was 40 years ago, now, people communicate much through social media. It just makes sense to use the medium. Its been very fruitful so far we've received several different responses. We believe is going to be quite useful as we move forward with the case."

But time has proven to be a benefit and a burden.

"We're looking at what we collected back in July of 1977. The more time goes on the better technology gets and we're able to analyze those smaller samples, if you will. "The only downside to that time is that people with information have moved away or passed on. The ending is getting the pieces of the puzzle the facts together that fit."

"My parents are getting older they would really like to know what happened, we're all getting older and would really like to know what happened," Tami Elzinga, Polinsky's sister told WZZM in February.

In February new forensic evidence revealed a woman was in Deborah's home at or around the time of the murder. Detectives have traveled across the country interviewing people about this case and they're confident this new initiative will bring additional information.
