David Kahl Biography, David Kahl Wiki
David Kahl is a registered sex offender who now stands accused in the 2008 stabbing and strangulation homicide of Brittany Zimmermann, a University of Wisconsin-Madison college student whose body was found in her apartment.
The criminal complaint makes it clear that Kahl was on authorities’ radar from the start, and they’ve allegedly had DNA evidence tying him to Brittany’s clothing for years. In repeated interviews with police, he described hustling young female college students for money to feed a crack cocaine addiction, saying he would knock on their doors and falsely claim that his car broke down, and he needed $40, the complaint contends. It also alleges that he admitted being inside Brittany’s apartment but claimed other homeless people committed the murder in a series of conflicting statements over the years.
David Kahl Age
He is 53 years old.
David Kahl Mother
His mother allegedly told police her son told her that he had been at Brittany’s house that day but “the two colored guys or the white girl went back where the girl had died.”
In 2014, his mother told police that her son told her that the guys with him had wanted the defendant to show them the places that people had been “nice” and that he did go back with these guys and that’s when the murder happened. He claimed he didn’t witness the murder.
His mother was living in Milwaukee. She said her son would scam to get drugs.
“Criminal charges were filed today in the murder of Brittany Zimmermann,” a statement from the Madison, Wisconsin Police Department read on March 20, 2020. “David A. Kahl, a 53-year-old male, has been charged in Dane County Circuit Court with First Degree Intentional Homicide (as a party to a crime and by use of a dangerous weapon).” Authorities have not explained why they chose to charge the case as a party to a crime.
University of Wisconsin-Madison college student Brittany Zimmermann Death
Brittany was killed on April 2, 2008, in her downtown Madison apartment. “Brittany’s killing shook the Madison community and devastated her family, friends, and hometown,” said the police statement. “It has been almost 12 years since Brittany’s death. During that time, MPD never gave up on her case, tirelessly pursuing justice for Brittany and her family.”
However, from the start, the case has involved questions about a 911 dispatcher’s handling of a frantic call from inside Brittany’s apartment, and why it took so long to charge Kahl due to the fact DNA and other evidence was developed years ago. Kahl’s name has circulated in the media for years, and, in 2016, Brittany’s parents confirmed a DNA match had been found in the long-languishing case. However, it took until 2020 for charges to result.
Zimmermann was a native of Marshfield, Wisconsin who was only 21 years old when she died. She was a student at UW-Madison who was majoring in Medical Microbiology and Immunology, according to the Madison police statement, which added, “She lived with her fiancee and their three cats in the 500 block of West Doty Street.”
Police added that investigators “have conducted hundreds of interviews, processed countless pieces of evidence, and produced thousands of pages of reports. The Dane County District Attorney’s Office and Wisconsin State Crime Lab have also been instrumental in the investigation. Investigators have conducted hundreds of interviews, processed countless pieces of evidence, and produced thousands of pages of reports.”
“The dedication and persistence of those tasked with investigating this case – past and present – has never wavered,” police wrote.
The complaint graphically describes the crime scene. Be aware that the details are very disturbing. Brittany resided at 517 W. Doty Street, along with her boyfriend, J.G., the criminal complaint says.
“Deputy Coroner Sholts reported that the manner of death of B.Z. was deemed to be homicide and that the cause of death was a combination of sharp force and blunt force injuries…the Madison Police Department received the Medical Examiner’s Autopsy report, authored by Dr. Robert Corliss. Dr. Corliss reports that he conducted the autopsy of B.Z. on April 3, 2008. The final anatomic diagnosis was ‘complex homicidal violence,’ including multiple sharp force injuries, evidence of ligature strangulation and blunt force injuries.”
According to the complaint, Dr. Corliss “reports that there were multiple stab wounds to the anterior chest. Dr. Corliss reports that there was a horizontal band consistent with ligature marking over the anterior neck, and surrounding the ligature mark were ‘superficial punctate hyperemic markings’ consistent with excoriations. Dr. Corliss reports that one side of B.Z.’s face, extending from the forehead to the chin, sustained contusional injury.”
Police determined that, after lunch, Brittany went on her computer. “Detective Murphy reports that she performed an analysis of the activity on April 2, 2008, on the computer located in a bedroom at 517 W. Doty Street. Detective Murphy reports that at 12:00 p.m., a UW website regarding financial aid was opened and at 12:01 p.m., (Brittany’s) email account was accessed. Detective Murphy reports that it appears that (Brittany) was on her computer and online from 12:00 p.m. on, and was fairly active on the computer until 12:18 p.m., when the computer activity stopped.”
David Kahl Criminal Record
According to the Madison police, Kahl “is incarcerated in the Wisconsin Prison System for unrelated charges and will be transported to Dane County in the future.”
He is a registered sex offender already on a lifetime registry requirement, according to the Wisconsin Sex Offender Registry. According to Wisconsin court records, the case is a second-degree sexual assault with a habitual criminality penalty enhancer that dates to 1993. In 2016, he was convicted of 7th offense drunk driving. He received a three-year prison sentence on that offense. He faced a slew of criminal charges over the years, including disorderly conduct and theft, and more serious charges, like felony drug dealing. He’s cycled through the Wisconsin prison system since at least 1992.
In an April 7, 2008 interview with police, recounted in the criminal complaint, Kahl allegedly said that “he had gotten out of prison approximately four months ago, had lived in a halfway house, and then had moved into his residence at 114 N. Franklin Street, apartment 1, in the City of Madison, approximately three months ago.”
He was accused of telling police that he “was diagnosed with paranoid schizophrenia approximately two to three years ago and is presently off his medication.”
He gave a series of police interviews over the years. In one, he claimed he was hanging out with other people who commit thefts and burglaries by calling through college kids’ windows when they aren’t home.
He stated that he was associating that day with a woman he was smoking crack with and two males who were with her. He stated that the woman told the two men they should return to the same area and obtain more money by robbing one of the college-aged females. It’s not clear from the complaint whether these three people really existed or whether police were able to track them down; however, they feature heavily into Kahl’s own stories of what happened that day, according to the complaint.
