On Sunday, October 10, 1999, Grace Harrington, the wife of a Mr. Kenneth Harrington, drove her husband to the emergency room of Mercy Hospital. When the nurses wheeled out a gurney, she told them she had barely been able to wake him up and then get him into her car. When the nurses wheeled Mr. Harrington into an examination room he was unresponsive but was still taking shallow breaths and had a very weak pulse. The emergency room doctor started his examination while Mrs. Harrington gave the desk nurse his name, age, and the fact that he'd had high blood pressure in the past. She also brought the bottle of a prescription he'd been given to control the high blood pressure.
About ten minutes after Mr. Harrington was wheeled into the examination room he went into cardiac arrest. The emergency room doctor attempted to revive him four times, but with no success.
Once Mr. Harrington had been declared dead, the emergency room doctor began attempting to determine a cause of death for Mr. Harrington's death certificate. He knew Mr. Harrington's heart had stopped beating, but not why. It was when he was reviewing the results of a blood tests they'd done as part of the diagnosis of Mr. Harrington's condition that he became suspicious and asked for a detective to be assigned to the case.
The blood sample had confirmed the information that Mr. Harrington had been taking Atenolol, a drug commonly prescribed for high blood pressure. What caused the doctor's suspicion that Mr. Harrington's death wasn't just a simple case of cardiac arrest was the concentration of Atenolol in his blood.
The normal concentration of Atenolol administered at the prescribed dosage level should have been about three milligrams per liter. The concentration of Atenolol in Mr. Harrington's blood was almost a hundred milligrams per liter. The doctor's diagnosis was that Mr. Harrington had been given or had taken an overdose of the drug, and the overdose had lowered his blood pressure to the point that his heart was starved for oxygen and just stopped pumping. That also explained why the attempts at restarting his heart had been futile.
His blood sugar was also extremely low, also a symptom of an overdose of Atenolol. It was the doctor's opinion that Mr. Harrington had either committed suicide by taking an overdose of Atenolol tablets or had been murdered. Per hospital procedure, the hospital contacted the police and Harry was assigned to figure out which was the case.
Harry talked to the emergency room doctor, and the doctor told him that to get that much Atenolol in his system, Mr. Harrington would have had to ingest at least fifty tablets at the same time, and probably more like sixty depending upon when he ingested them.
The doctor also told Harry something else that made Harry question the circumstances of Mr. Harrington's death. The doctor said Mr. Harrington didn't have any identification on him when the EMT's brought him to the ER, and that his wife had given Admitting her husband's name and their address. She didn't have the name of their insurance carrier so she said she'd have to call them back with that information. After Mr. Harrington died, the doctor had gone to the waiting room to tell her that Mr. Harrington had passed way. He wasn't able to do that because she'd left.
Harry's next stop was to speak with Mrs. Harrington. He'd planned to tell her that the doctors hadn't yet determined a cause of death and then observe her reaction. He also intended to ask her about any medical or mental problems Mr. Harrington had. Though Harry had his doubts, it was possible that since Mr. Harrington had been prescribed the medicine, he would have known the outcome of an overdose and had decided to take his own life.
When Harry knocked on the door of the Harrington house, he didn't get an answer. After knocking twice more, he walked next door to talk to the neighbor. The neighbor said when he walked out to get his newspaper at about nine, he saw that Mrs. Harrington's car wasn't in their drive. He hadn't seen her come back. He didn't know much about the couple except that Mr. Harrington worked construction and had told him he'd just finished up a job in Nashville and was now working on a new building in Knoxville.
Harry left his card on the door with a note asking Mrs. Harrington to call him. When she didn't the next day, Harry still wasn't too concerned. He knew it takes some time to make funeral arrangements and thought Mrs. Harrington was probably doing so. He called the hospital to see which funeral home had picked up the body. If Mrs. Harrington wouldn't come to him, he'd catch up to her after the funeral and burial ceremony.
When Harry called the funeral home, he learned that they had Mr. Harrington's body but Mrs. Harrington hadn't requested a visitation, funeral, or graveside service. All she'd requested and paid for was the embalming of his body, the least expensive casket they had, and a burial plot and vault. The funeral director said he thought it unusual that she'd paid the five thousand dollar cost in hundred dollar bills instead of writing a check.
Harry went to the cemetery on the day of the burial, that Wednesday, thinking that Mrs. Harrington would be there. The only thing he saw was some canvas screens around the grave and a backhoe operator waiting to fill in the grave after the people from the funeral home left. When she wasn't, he was pretty sure she'd poisoned her husband with Atenolol and then fled to avoid prosecution. He was more positive when he went back to the Harrington house that same day. He didn't get an answer when he knocked, so he started looking in the windows.
What Harry saw was nothing -- no furniture, no pictures on the walls, no rugs on the floor. He went next door to speak with the same neighbor as before and the neighbor said the day after he hadn't seen Mrs. Harrington's car in their drive, two big U-Haul trucks pulled up in the drive. The truck drivers and two other men unlocked the front door and than began taking things out of the house and putting them into their trucks. At about five, they closed up their trucks, locked the front door, and left.
Harry was sure then that Mrs. Harrington had killed her husband and had been busy erasing anything that could connect her to Knoxville or her husband. He got the VIN and license numbers for the 1990 Toyota owned by Mr. and Mrs. Harrington, and had put out a BOLO on the car. His intent was to arrest her on suspicion of murder.
Two days later, a patrol officer in Bristol looking to buy a car for his daughter stopped by a used car dealership and saw a Toyota that was the same color as the Toyota on the BOLO. When he checked the VIN number, it was the missing Toyota.
The car dealer told him he'd bought the car a couple days earlier from a woman. She had the title and what she wanted for the car was about fifty percent of its retail value, so he bought it. He'd paid her in cash and then driven the car into his lot to park it. When he came back, the woman was gone. He couldn't tell the officer much about her other than she was about average height, not skinny or fat, and had brown hair.
Harry kept trying to find Mrs. Harrington for the next two weeks, but found nothing. He was able to get her bank account information and the statements for her two credit cards. Those only reinforced Harry's opinion. The day of Mr. Harrington's death, their bank account had been closed, about fifteen thousand dollars, and she hadn't used either of her two credit cards since that date. Harry figured she'd closed the bank account and was paying for everything in cash because she didn't want to leave a paper trail of credit card charges.
Harry had one last way to find her, though it was a long shot. He got a court order to search the house and had the Crime Scene techs dust everything for prints and to look for anything that might have DNA. They found a bunch of fingerprints and also found some hair in both the bathroom sink and shower drains.
When they went outside, they found more prints on a trash can, and inside the trash can, an empty prescription bottle for Atenolol with Mr. Harrington's name as the patient. The prescription had been written by a doctor in Knoxville, and had been filled by the local Walmart a week earlier. Harry figured that prescription was his murder weapon.
Harry sent the prints and hair samples to the TBI along with the request that if they found any matches to give him a call. He figured that at worst, at least the prints and DNA would end up in the TBI database and that someday, some other detective would have prints or DNA that matched along with a name. If that happened, he'd have a lead he could pursue.
