The sister of a suburban Detroit businesswoman whose torso was found in her garage last month has filed a $50 million wrongful death lawsuit against Stephen Grant, the suspect in his wife's killing.

Alicia Standerfer, the sister of Tara Lynn Grant, seeks to revoke Stephen Grant's claims to the couple's home, two life insurance policies naming him as his wife's beneficiary and a 401(k) plan, among other assets. Standerfer, of Chillicothe, Ohio, was named Monday as personal representative of her sister's estate and conservator for her two children, ages 4 and 6.

"He left his two children without a mother or their home or any real sense of normalcy," Standerfer told The Macomb Daily for a story published Thursday.

Grant, 37, is in jail awaiting a May 15 preliminary hearing on charges of murder and mutilation of a corpse. He is accused of killing his 34-year-old wife on Feb. 9 and later dismembering her body, parts of which were found in a park near their home.

Tara Grant's torso was found March 2. Stephen Grant was captured two days later in a state park at the northern tip of Michigan's Lower Peninsula.

The civil suit, filed in Macomb County Circuit Court, also seeks compensation for funeral, burial and other costs incurred by Tara Grant's family.
