The boyfriend of a 19-year-old woman who was found dead six days before the death of her younger sister was arrested Tuesday on a preliminary charge of murder.

James McFarland Jr., 23, was being held without bond at the Wayne County Jail in Richmond on one count of murder.

McFarland was the boyfriend of Erin Stanley, 19, who died Sept. 1 at her parents' home in Centerville, just west of Richmond in east-central Indiana. Her sister, Kelly Stanley, 18, was found dead in the home on Sept. 7.

A Centerville police dispatcher said McFarland was charged in Erin Stanley's death.

McFarland was the father of Erin's infant daughter and lived with the Stanleys in Centerville. He was arrested about 4 p.m. Tuesday at a residence in nearby Cambridge City, police said.

McFarland denied any involvement in either woman's death in an interview last week with the Palladium-Item of Richmond. He said he planned to marry Erin Stanley and was devastated by her death.
