Bio

David M. Keen was born on June 5, 1962. He was identify as a white male convicted in Shelby County, Tennessee, for first-degree murder. Before the killing of Ashley Nicole “Nikki” Reed, Keen lived in Millington, Tennessee, with his fiancée, Deborah Wilson, in a three-bedroom mobile home. Deborah’s four children, including Nikki, also lived in the home, along with Deborah’s parents.

Keen’s childhood and mental health history later became important issues during the sentencing phase of his capital case. His adoptive parents testified that he was malnourished when they adopted him at age four. They described him as nervous, emotionally troubled, and socially withdrawn. He was later diagnosed with attention deficit disorder and was treated with Ritalin while in school. His family also testified that his biological father was abusive and that the children moved repeatedly because the father was wanted for theft and child neglect.

During resentencing, Keen’s relatives described severe physical and emotional abuse during his early childhood. Testimony included claims that the children were beaten with cords and lumber and that Keen had also been placed in an abusive foster home before adoption. A clinical psychologist diagnosed him with post-traumatic stress disorder, serious depression, and attention deficit disorder. The psychologist also testified that Keen showed some signs of pedophilia, although he did not find enough evidence for a full diagnosis.

Keen dropped out of high school during his junior year and later joined the United States Navy. By the time of the murder, he was 27 years old and living in the same household as Nikki Reed, the 8-year-old daughter of his fiancée. His position in the household gave him access to the child and allowed him to offer to check on her when family members became concerned about her overnight plans.

Murder Story

In March 1990, David M. Keen was living in Millington, Tennessee, with his fiancée, Deborah Wilson, and members of her family. Deborah’s 8-year-old daughter, Ashley Nicole “Nikki” Reed, was also part of the household. On the evening described in the Tennessee Supreme Court record, Keen and Deborah went with her parents to the VFW Club in West Memphis, Arkansas, for dinner and bingo. The children were supposed to be staying with friends. When Deborah’s father, Jessie Wilson, became concerned about Nikki’s overnight plans, Keen offered to drive back to Millington to check on her. Wilson allowed Keen to borrow his car.

Keen left the VFW Club at about 5:30 p.m. and returned about two hours later. When he came back, he told the family that Nikki was spending the night with her friend Shantell. Later that night, Jessie Wilson noticed that a green blanket usually kept in his car was missing. When he asked Keen about it, Keen said he had moved the blanket to the back seat because he did not want to sit on it.

The next morning, Nikki’s grandmother went to pick her up for church and learned that Nikki had not spent the night at her friend’s house. Family members began searching the mobile home park. Keen and Deborah later joined the search. After the search failed, Deborah and Keen went to the police station to report Nikki missing. While waiting for them to return, Nikki’s grandparents found a pair of panties on the passenger-side floorboard of Jessie Wilson’s car. They left the item in place and reported the discovery to police.

Investigators questioned Keen. He first denied involvement, but later admitted that he had thrown Nikki into the river. He led police to the north end of Mud Island in Memphis, near the Wolf River, where officers found Nikki’s naked body wrapped in the missing green blanket. A blue denim skirt and pink shirt were found with the body, but police did not find her panties.

Keen later gave a more detailed confession. He said he had found Nikki and intended to take her back to West Memphis. During the drive, he stopped the car, removed her clothes, undid his pants, and attempted to sexually assault her. He admitted holding his hand over her throat and said Nikki struggled for a short time. He stated that she turned blue and was no longer breathing. He then tied a shoelace around her neck, removed it, wrapped her body in the green blanket, and dumped her into the river before returning to West Memphis and telling the family that Nikki was staying with a friend.

The medical evidence showed that Nikki suffered multiple scrapes and bruises to her face and neck, a deep ligature mark around the front of her neck, injuries to her genital area, and a tear to the posterior wall of the vagina. Sperm heads were found inside the vagina. The medical examiner testified that Nikki was alive while she was raped and injured, although he could not say whether she remained conscious through the entire attack. The autopsy also found fluid in her lungs, and the medical examiner testified that, in his opinion, she was alive when she was placed in the water. Ligature strangulation was identified as the actual cause of death.

In February 1991, Keen pleaded guilty to first-degree murder in the perpetration of rape and aggravated rape. A Shelby County jury sentenced him to death for the murder and to 20 years in prison for aggravated rape. On automatic appeal, the Tennessee Supreme Court reversed the death sentence because the trial judge failed to properly instruct jurors that aggravating circumstances had to outweigh mitigating circumstances beyond a reasonable doubt. The conviction remained in place, but the case was sent back for a new sentencing hearing.

At the second sentencing hearing, prosecutors relied on two aggravating circumstances: that Nikki was under 12 years old while Keen was over 18, and that the murder was especially heinous, atrocious, or cruel because it involved torture or serious physical abuse beyond what was necessary to cause death. The defense presented mitigating evidence about Keen’s childhood abuse, mental health history, attention deficit disorder, depression, and psychological trauma. On August 15, 1997, a jury again sentenced Keen to death.

On October 5, 2000, the Tennessee Supreme Court affirmed the death sentence after resentencing. The court held that the aggravating circumstances were supported by the evidence and that the death sentence had not been arbitrarily or disproportionately applied. Later appeals focused heavily on claims of intellectual disability and whether Keen could reopen post-conviction proceedings based on later IQ evidence. Tennessee courts rejected those efforts, and in July 2020 the U.S. Supreme Court declined to hear a later appeal.
