A dark and deeply unusual chapter in the family history of Minnesota Democratic Senate candidate Peggy Flanagan has entered the campaign just weeks before the midterm elections. The development concerns her maternal grandfather, John Jacob Hartmann, and decades of troubling newspaper reports and court records.

Alpha News reported that Hartmann spent decades in psychiatric custody, escaped twice, and was suspected in multiple killings, although he was never charged in those deaths. It remains unclear whether voters will hold allegations involving Flanagan’s long-dead grandfather against the candidate herself.

Flanagan, Minnesota’s lieutenant governor, is running against former television sports reporter Tafoya for the Senate seat held by Democrat Tina Smith, who is retiring. Neither Flanagan nor Tafoya has publicly commented on the resurfaced allegations.

The story has nevertheless generated attention on social media. Turning Point USA spokesman Andrew Kolvet highlighted the "violent mental illness in Minnesota Democrat Peggy Flanagan's family," in an X post alongside a photograph of Flanagan wearing a shirt that says "Protect trans kids."

Town Hall columnist Dustin Grage wrote that the report "adds up." The family history has emerged as Flanagan also faces criticism over her progressive activism and outreach amid Minnesota’s sprawling fraud controversy.

Flanagan has frequently discussed her upbringing, including being raised by a single mother who relied on SNAP benefits and housing assistance. She has also spoken about the influence of her Indigenous father, a tribal land rights activist who helped inspire her advocacy for Native American communities.

The story involving Hartmann offers a far darker look at another branch of her family. Minneapolis newspapers reported throughout the 1970s and early 1980s on his psychiatric confinement, escapes, and alleged links to at least four killings.

Flanagan was three years old when Hartmann died on Feb. 6, 1983. A Minnesota Star Tribune death notice listed Flanagan’s mother, Patricia Hartmann, and her three sisters, Kathleen, Mary and Margaret, as his surviving daughters.

An obituary for Patricia, who died in 2022, listed Hartmann as her maiden name and identified John as her father. Flanagan told Minnesota Women’s Press that her mother and grandmother were both single mothers, describing her grandmother as having raised four daughters "at a time when that didn’t happen a lot."

Flanagan’s mother later married Thomas Flanagan, who was identified as Peggy Flanagan’s stepfather in his obituary. The family records cited in the reporting connect Hartmann to Flanagan through her mother.

A Feb. 9, 1983, newspaper article announcing Hartmann’s death said he was committed on Nov. 1, 1951, after his wife filed a petition claiming he was "mentally ill and dangerous." The commitment followed the discovery of Theodore Foth’s body burning in his room, but Hartmann was never charged in Foth’s death.

The newspaper also identified Hartmann as a suspect in the 1964 murder of another patient at the Minnesota Security Hospital. Once again, Hartmann was never charged.

Hartmann was transferred to Anoka State Hospital in 1970 but escaped to New Mexico, where a newspaper reported he was suspected in the deaths of a man and a woman. A 1973 Eighth Circuit Court of Appeals ruling did not mention those alleged killings.

Instead, the ruling said New Mexico authorities detained Hartmann under a warrant issued by Minnesota Probate Judge Melvin Peterson in September 1970. Authorities found that Hartmann was living in New Mexico "without incident and without hiding his identity following his escape in Minnesota."

A special prosecutor later released Hartmann after finding that he was "sane and safe to be at large." Hartmann was apprehended in Colorado the following year on a misdemeanor charge and returned to Minnesota.

In April 1979, Hartmann failed to return from a visit pass at the Minnesota Security Hospital and fled to Missouri. There, he allegedly threatened U.S. District Judge Miles Welton Lord during a telephone call.

Lord had presided over Hartmann’s earlier federal challenge to his involuntary return from Colorado to Minnesota and initially dismissed claims against several Minnesota officials. Federal authorities charged Hartmann over the alleged threat, according to a 1979 Star Tribune article.

The revelations inject a bizarre family history into an already heated Minnesota Senate contest, though the allegations concern a grandfather who died when Flanagan was a young child.
