Neola Robinson is charged in the death of her husband Ervin Robinson, who was reported missing by his employer in May 2010.
Lonny Haschel, a spokesman for the Texas Department of Public Safety, says Texas Rangers arrested Robinson on Saturday. Haschel says they exhumed the husband's remains Tuesday from the yard of their mobile home in Pelican Bay, about 20 miles northwest of Fort Worth.
Robinson is being held in the Tarrant County Jail with bond set at $150,000.
Online jail records listed no attorney for the widow.
