Decades-long murder sentence for Iowan who put victim in car, crashed in southern Minnesota

The victim was a DJ and “community and trans activist,” a friend said shortly after the murder in June 2024.

An Iowa woman has received a 40-year term for killing a woman in a Minneapolis apartment, then taking the victim’s car and crashing it in southern Minnesota with her body inside.

Margot G. Lewis, 33, was sentenced Thursday in Hennepin County District Court after being convicted of second-degree murder in connection with the June 2024 stabbing death of Liara Tsai, 35, inside the victim’s home in the 700 block of E. 16th Street.

With credit for time in jail since her arrest, Lewis is expected to serve roughly 25½ years in prison and the balance on supervised release.

Lewis, of North Liberty in east-central Iowa, was also charged in Olmsted County, where the crash occurred, with felony interference of a dead body. In light of the murder sentence, prosecutors on Friday dismissed that case.

Neither criminal complaint mentioned a motive for the killing. Tsai’s former spouse told police that Lewis flew in from Boston on June 21, 2024, for an eight-day stay with Tsai, the murder charge noted. The former spouse added that Lewis and Tsai had a “sordid and emotionally challenging” relationship.

Steven Seuling, a friend of Tsai’s, told the Minnesota Star Tribune soon after the killing that she worked for him at times as a DJ at various events. He added that Tsai was a “community and trans activist. She was very, very much more than just a DJ.”

A deputy sent on June 22, 2024, to the crash scene along Interstate 90 south of Eyota saw Tsai’s car in the center median and Lewis sitting in a folding chair that a bystander provided. The deputy determined she was speeding when the car hit a guardrail.

In a search warrant affidavit filed by the State Patrol seeking permission to inspect the car’s data recording devices, a sergeant wrote that crash scene evidence indicated Lewis “traveled for quite some time [in the median]. ... The vehicle did not appear to make any maneuvers to prevent the crash.”

The deputy opened the car’s passenger-side back door and saw Tsai’s body on the folded-down seat. It was wrapped in a bed sheet, blanket, futon-style mattress and a tarp.

A dog was wandering around the crash scene, and its microchip was linked to Tsai’s address.

Minneapolis investigators searched Tsai’s apartment and found blood in several places. A bloodied plastic and metal object was on the bed. A knife was missing from a butcher block in the kitchen.

Surveillance video from outside Tsai’s apartment showed Lewis leaving at about 4:35 a.m. June 22, 2024. Lewis was driving with a dog in the front passenger seat.

Following the crash about 7 a.m., Lewis was taken to a nearby hospital for medical treatment. She spoke to neither hospital staff nor law enforcement.

Upon being moved to the Olmsted County Sheriff’s Office, Lewis sat in a ball on the floor. When told that officers intended to carry out “evidence collection from [her] person,” she physically resisted. Lewis balled up her hands after being told that officers intended to collect fingernail clippings from her, apparently for DNA testing.
