Two additional suspects have been arrested following an investigation into the 2011 death of Nancy Harvill.

Dallas County Sheriff’s Investigator Chuck Barker said Christopher Aldrich, who was Harvill’s stepbrother, and Sherri Bowen, Harvill’s stepmother, were taken into custody Friday and after a court appearance Monday, will be held on bonds of $250,000 each.

Both Aldrich and Bowen are being held on probable cause of capital murder, kidnapping, first-degree domestic battery and hindering apprehension or prosecution. Aldrich is also charged with abuse of a corpse, while Bowen has also been charged with financial identity fraud and two counts of contributing to the delinquency of a minor.

Last week, John Aldrich, who is also a stepbrother of Harvill, was arrested and held on probable cause of second-degree murder. Those allegations have been upgraded to capital murder, kidnapping, first-degree domestic battery, hindering apprehension or prosecution, two counts of terroristic threatening and abuse of a corpse.

Barker said the incident began on or about Aug. 26, 2011, when Nancy Harvill, 34, and John Aldrich, 25, were engaged in a physical altercation that resulted from an argument over the care and treatment of Nancy’s minor children. It is alleged that Bowen instructed John and Chris Aldrich to tie up Harvill.

“The two suspects bound Nancy’s hands behind her back, then tied her feet together in a hogtie fashion,” a news release from Barker said. “All three suspects then began to beat and torture Nancy Harvill by striking her repeatedly with their hands, broom sticks, baseball bats, cast iron pans, furniture, hot candle wax, kicking and shooting her with a spring loaded airsoft gun. The continued abuse and torture ultimately led to her death.”

Barker said Bowen instructed other family members to participate by punching and kicking Harvill while she was bound and on the floor.

“The torture continued over the next 48 hours while Nancy remained bound and abused,” the release said. “She was not permitted to eat, drink, or use the restroom and had been transported between the laundry room and living area for periods of abuse and torture.

“On Sunday, Aug. 28, 2011, between the hours of 10 a.m. and 2:30 p.m., following her torture and subsequent death, Nancy was laid out in the laundry room where they straightened out her body and retied her,” the news release said. “They then dragged Nancy’s corpse through the house, and out a back door leading into a shop like addition to the family home.”

Barker said John and Christopher Aldrich used a borrowed tiller to excavate the ground and two shovels to shape the grave.

“Nancy was wrapped in plastic, her body was contorted and placed in the grave,” the release said. “Once Nancy was buried, John Aldrich, Christopher Aldrich and Sherri Bowen met inside the house and developed a cover-up story that Nancy had left the state with an unknown individual,” Barker said in the news release. “The cover-up story was maintained over the next 15 months. Meanwhile, financial, medical and personal matters were falsified using the deceased’s identity in an apparent effort to conceal her death.”

Court appearances for all three suspects are set for 9 a.m. Wednesday, Feb. 20, at the Dallas County Courthouse.
