Police said on Wednesday that a man’s body found in Alabama may be linked to four murders in Tennessee. On Monday, Tennessee officials found three women and an 18-month-old boy dead in Lincoln County, about 100 miles south of Nashville. One day later, authorities found the body of Warren Vincent Crutcher, whose 3-year-old son survived the attacks, in Alabama. The 3-year-old boy had called relatives on Monday morning, saying he couldn’t wake anyone up in his house. When authorities arrived, they found the bodies of his mother, Chabreya Campbell, 22, and her 18-month-old son, Rico Ragland, as well as Amber McCaulley, 21, of Huntsville, Ala. Hours later, the body of 21-year-old Jessica Brown was found at her home in Fayetteville, Tenn. The cause of death for all four is still unknown.
