A Minnesota man has been taken into custody in connection with the investigation of a woman’s death inside a camper.
Stanley Munstermann, 69, faces second-degree murder charges and was detained at the Wabasha County Jail on February 26. This arrest comes months after the discovery of 66-year-old Barbara McBride-Law’s body in a camper at a Mazeppa campground, located roughly 70 miles southeast of Minneapolis. According to the Wabasha County Sheriff’s Office, McBride-Law was found deceased on August 30, 2025, inside a camper near Mac’s Park Place, a bar within the campground. Although no visible injuries were initially noticed, the medical examiner later confirmed that she died due to homicidal violence.
As reported by local ABC affiliate KSTP, court documents revealed that authorities discovered Munstermann had been staying with McBride-Law at the campground. When contacted by police the day following the discovery of McBride-Law’s body, Munstermann claimed he was at his girlfriend’s home in Nebraska. He described his relationship with McBride-Law as a long-term friendship dating back to their high school years, clarifying that it was not romantic.
Investigators noted that surveillance footage captured Munstermann’s arrival at the campground on August 28, 2025, and his departure at 3:47 a.m. on August 30, 2025, just hours before the body was found. Munstermann admitted to police that he had been drinking heavily on the night of August 29, 2025, and could not recall entering McBride-Law’s camper.
Witnesses reported to police that Munstermann allegedly made disturbing remarks following McBride-Law’s death. He reportedly told one individual that he thought he might have killed someone but could not remember. During another phone conversation, Munstermann allegedly expressed concern that he might have seriously injured someone, though he was unsure who it was.
On Feb. 26, months after McBride-Law was laid to rest, Munstermann was charged with her murder. He was booked into the Wabasha County Jail on two counts of second-degree murder and one count of manslaughter. Local NBC affiliate KTTC reported that his arraignment was scheduled for Monday.
