FOND DU LAC (WITI) -- Fond du Lac County Sheriff’s detectives have arrested Dennis Brantner for the 1990 homicide of Berit Beck.

61-year-old Brantner was taken into custody on Friday morning, March 27th on an arrest warrant for first degree murder -- a year after he was named a suspect in the case. Brantner was arrested at the Kenosha County Courthouse.

Beck was 18 years old when she disappeared while traveling from Sturtevant to Appleton. Her body was found in a ditch in Fond du Lac County.

For decades, Beck's family experienced unthinkable pain as police continued to search for her killer.

In April of 2014, there was finally a lead.

The Fond du Lac County Sheriff's Office announced new evidence revealing Brantner was in the van Beck was driving when she disappeared.

Authorities say Brantner's co-worker told authorities the 61-year-old had a photo of Beck in his workspace.

Brantner was in court on Friday for an unrelated charge of felon in possession of a firearm.

More details are expected to be released in this case on Monday. A news conference has been scheduled for 11:00 a.m. in Fond du Lac.

The Kenosha Police Department and Kenosha County Sheriff’s Office assisted with the arrest.

Berit Beck’s family has been notified of Brantner’s arrest. Beck’s parents Dave and Diane, their son Ben, and the entire Beck family have issued the following statement:

"We are encouraged and relieved for this day to have arrived for Berit and our family. We request that our privacy be respected as this process unfolds."

    It’s a long time to wait for justice, but I’m so glad that the sheriff and police didn’t give up on this old case. I remember it from just after I graduated college. My neighbor in Sun Prairie said that she worked for the same company as Beck. Apparently Beck was a new employee, but never showed for her computer training. It was the first experience I had with missing women, which unfortunately is a feature of American life. And although I’m glad that the suspect was finally identified and caught, I have to wonder how many other missing girls he’s been involved with through the years.

    Took a while but props to the police for not giving up. He should be thrown in a ditch somewhere instead of tax payers paying for his life behind bars, eating, medical care, etc etc. Scum

    This guy is nothing but a trailer trash scumbag and deserves the death penalty. My heart goes out to the family who have had to live this nightmare for 25 years. May they find some level of comfort in knowing this scumbag has been charged and will hopefully be convicted of Berit’s murder.

    Like to see him die a slow painful death just begging for his life as he is tortured and dimembered

    Wisconsin needs to bring back the death penalty. C’mon governor! The people are sick of seeing this day in a day out, and then paying for these POS murderers to live better in prison than they did on their own.
