A homicide investigation is underway in Minneapolis after law enforcement responded to a weekend motor vehicle crash in southeastern Minnesota and discovered a victim whose traumatic injuries weren’t consistent with a car accident.

While responding to the single-vehicle crash Saturday morning near the Eyota exit on Interstate 90, the Olmsted County Sheriff’s Office found a body in the back seat of the car, according to a press release.

The driver, 32-year-old Margot Lewis, was outside the vehicle and being tended to by a passerby. While checking to see if anyone else was in the vehicle, deputies found the body of a 35-year-old woman.

According to the sheriff’s office, the condition of the body was “suspicious” and it was “immediately apparent” the woman’s death wasn’t a result of the crash.

Lewis was eventually arrested for interference with a dead body.

Meanwhile, Minneapolis police were asked later Saturday to perform a welfare check at the dead woman’s home in the 700 block of 16th Street Southeast. According to Minneapolis police, authorities eventually executed a search warrant, and the scene inside the residence showed evidence of violence.

Lewis remains in custody ahead of a Tuesday court appearance.

The name of the victim is being withheld pending autopsy and notification of next of kin.
