CORUNNA, Mich. (AP) — A Michigan woman is charged after authorities say they believe she kept her disabled adult sister locked in a closet for several years with little food or water and a bucket to urinate in.

Shiawassee County’s chief assistant prosecutor Daniel Nees tells The Associated Press 44-year-old Candy Lawson of Corunna faces charges including unlawful imprisonment and vulnerable adult abuse. She’s due back in court in a few weeks.

The court says Friday she didn’t have a lawyer on record.

Nees says police responded to a home July 9 following an anonymous tip and found the 42-year-old sister malnourished and dehydrated. She was hospitalized.

Corunna police Chief Nick Chiros tells The Argus-Press of Owosso he’s “never seen an adult abuse case of that type” in his 35 years in law enforcement.
