An Ohio man was sentenced to 20 years in prison for using the word “poison” to describe the onion and garlic he ate in an apparent case of mistaken identity.

Timothy E. Brown, 38, of Litchfield Township, Ohio, pleaded guilty last week to a charge of false reporting in the death of his 21-year-old girlfriend, Samantha Sturgis, who died from acute poison ivya poisoning in August 2015.

According to court documents, Brown admitted to eating three pounds of onions and one pound of garlic in the first 24 hours of her death.

He was sentenced on Monday.

Sturgis was found dead on Aug. 20, 2015, in her apartment with signs of severe poisoning.

The toxic substances in the apartment included a mixture of the toxin and the poisonous compound, cyanide.

The Ohio Department of Health and Human Services investigated Brown’s claims and found that Brown had not consumed any poisonous substances.

The state said Brown had used the word poison three times in the last two months of the case.

In November, Brown told investigators that he believed the onions and the garlic were poisonous, according to a court document.

Brown was also told that he had eaten a package of the poisonous chemicals.

Streatis’ death sparked a nationwide investigation that resulted in the arrests of several suspects, including Brown and his wife, Angela Brown, who were charged with her manslaughter.
