Biography
Mark David Hortman was an information-technology program manager in Minnesota and the husband of Melissa Hortman, Speaker Emerita of the Minnesota House of Representatives. He was killed alongside his wife at their home in Brooklyn Park, Minnesota, on June 14, 2025.
Early Life and Education
Hortman was born on November 30, 1966, in Atlanta, Georgia, to J. Carroll Hortman and Ruth Russell, and grew up in Raleigh, North Carolina. He graduated from Millbrook High School in 1984, attended North Carolina State University, and then earned a bachelor’s degree in physics with a minor in computer science at the University of North Carolina at Chapel Hill, whose alumni association records him as a member of the class of 1989. He later earned an MBA from the University of Minnesota’s Carlson School of Management in 2011.
Career
His first job was on an IBM team rewriting the federal air traffic control system in Washington, D.C. It was there that he met Melissa Haluptzok; they married on August 13, 1993, and he lived in Minnesota for more than three decades afterward. The couple had two children, Colin, born in 1997, and Sophia, born in 1999.
From January 2021 he worked as a program manager at nVent Electric, a St. Louis Park, Minnesota-based company that makes electrical products, where he managed a team of software engineers and, according to his LinkedIn profile as quoted by Twin Cities Business, worked on replatforming content-management systems and relaunching e-commerce websites. After his death, nVent said he had been “a valuable member of our Twin Cities-area team” who “worked closely with colleagues globally.” He was also a partner and board member of Gray & Creech Inc., a family-owned North Carolina office-solutions business.
Death
On the night of June 13, 2025, the Hortmans attended the Minnesota DFL’s Humphrey-Mondale Dinner in Minneapolis. In the early hours of June 14, according to the account the U.S. Attorney’s Office drew from the federal charging documents, Vance Luther Boelter — disguised as a law enforcement officer and driving a black Ford Explorer fitted with police-style lights — shot State Senator John Hoffman and his wife Yvette Hoffman at their home in Champlin, then drove to two other elected officials’ homes without making contact, and then to the Hortman residence in Brooklyn Park. Local officers, alerted by the Champlin shooting, arrived to conduct a safety check and saw Boelter standing outside the front door. He fired several shots into the house, repeatedly striking Mark Hortman, then entered and fired further shots striking Melissa Hortman. Both died of their wounds. Mark Hortman was 58.
Boelter was arrested near Green Isle, Minnesota, on the evening of June 15, 2025, after a two-day search.
The Federal Prosecution
Boelter was charged by federal complaint on June 15, 2025, and indicted on six counts on July 15, 2025, covering the stalking and murders of Melissa and Mark Hortman, the stalking and shooting of John and Yvette Hoffman, and the attempted shooting of the Hoffmans’ daughter Hope. He pleaded not guilty at his arraignment on August 7, 2025, and pleaded guilty to all six counts on June 11, 2026. On July 23, 2026, U.S. District Judge John R. Tunheim sentenced him to two consecutive terms of life imprisonment plus a consecutive 40-year term; judgment was entered on August 5, 2026 and amended on August 7, 2026. The U.S. Attorney’s Office described the six offenses of conviction as stalking resulting in death, murder through use of a firearm, and discharging a firearm during crimes of violence.
What Is Not Established Here
Removed for want of a source meeting this project’s standard: the claim that Hortman worked at Digital River as a “principal enterprise program manager” on e-commerce and API strategy programs. The affiliation and the job title appear to trace to his LinkedIn profile, which is not publicly retrievable and has no Wayback capture; no source that could be fetched and read confirms it, so Digital River has been dropped from the page and from the affiliations field. Also removed: the summary statement that he “worked in the information technology and e-commerce industries for over three decades,” which no source asserts in those terms.
Corrected: the description of the attack. The page previously said Boelter “targeted the Hortmans’ residence” without stating the sequence the charging documents describe, and it presented the case as a pending allegation; the federal case is now concluded, with a guilty plea and sentence, and the page says so. The page also previously stated only that Boelter “attacked” the Hoffmans, omitting that the indictment included an attempted-shooting count as to their daughter.
One conflict in the record is left open rather than resolved: the family obituary gives 1986 as the year of his UNC degree, while UNC’s own alumni association identifies him as class of 1989 and Twin Cities Business reports 1989. This page uses 1989.
Not covered here: the Minnesota state charges filed against Boelter in Hennepin County and their disposition. Contemporaneous reporting quoted the Bureau of Criminal Apprehension describing state murder and attempted-murder counts, but no state court record or prosecutor’s filing confirming their current status could be retrieved, so the page makes no claim about them.
