A 32-year-old Iowa woman was charged on Tuesday with concealing the body of Liara Tsai, 35, of Minneapolis.

Court records show that Margot Lewis made her first appearance in Olmsted County Court Tuesday morning.

According to a criminal complaint, authorities were called to a one-vehicle crash at the intersection of I-90 and Highway 42 in Olmsted County on Saturday.

Based on tire tracks, authorities believe the driver, identified as Lewis, was speeding eastbound on I-90 when she went into the median.

Bystanders told responding deputies there appeared to be a deceased or injured person in the car.

Inside, deputies found a body wrapped in a bed sheet, a blanket, a futon-style mattress and a tarp, court documents state. The person, later identified as Tsai, was obviously deceased and authorities said she didn’t seem to have been killed in the crash. She was cold to the touch and there was dried blood on the blanket.

Investigators later found a large wound on the right side of Tsai’s neck.

Lewis was medically cleared at the hospital and then booked into Olmsted County Jail. She did not respond audibly to law enforcement.

Lewis’ mugshot is not yet available on the Olmsted County Jail roster. This article will be updated when it becomes available.

The Medical Examiner confirmed on Sunday that Tsai was killed before the car crash.

Monday evening, Minneapolis police and members of the Minnesota Bureau of Criminal Apprehension executed a search warrant of Tsai’s home on 16th Street East and found a scene “indicating violence.”

Investigators have not announced any arrests for Tsai’s death.
