Alex Christopher Ewing: The Colorado Hammer Killer
Background
Alex Christopher Ewing is an American serial killer whose name became associated with a terrifying series of home invasions and hammer attacks committed in Colorado during January 1984. His confirmed murder victims were Patricia Louise Smith and three members of the Bennett family: Bruce, Debra and their seven-year-old daughter, Melissa. Ewing also attacked several people who survived, including the Bennetts’ three-year-old daughter, Vanessa.
The Colorado murders remained unsolved for more than three decades. Ewing was eventually identified through DNA evidence while he was serving a lengthy prison sentence in Nevada for an unrelated home invasion and attack. The development of modern forensic testing allowed investigators to compare DNA preserved from the Colorado crime scenes with Ewing’s DNA profile. This connection led to his extradition to Colorado, separate murder trials and convictions in 2021 and 2022.
Confirmed Murder Victims
- Patricia Louise Smith, age 50 — Killed on January 10, 1984, inside her townhouse in Lakewood, Colorado. Smith, an interior designer, was sexually assaulted and beaten to death with an auto-body hammer.
- Bruce Bennett, age 27 — Killed during the night of January 15–16, 1984, inside the Bennett family home on East Center Drive in Aurora, Colorado. His body was discovered on the morning of January 16. He died from blunt-force and sharp-force injuries.
- Debra Bennett, age 26 — Killed during the night of January 15–16, 1984, in the family’s Aurora home. She was discovered on January 16 and died from severe blunt-force trauma.
- Melissa Bennett, age 7 — Killed during the night of January 15–16, 1984, in her bedroom at the Bennett home in Aurora. She died from blunt-force and sharp-force injuries and had also been sexually assaulted.
The January 1984 Attacks
Ewing’s known Colorado crime spree began during the first days of January 1984. His attacks followed a frightening pattern: entering occupied homes at night, approaching victims while they were sleeping or otherwise vulnerable, and striking them repeatedly with a hammer or another heavy object. The apparent randomness of the attacks made the crimes particularly difficult to investigate. There was no obvious personal relationship between Ewing and the families whose homes he entered.
On January 4, 1984, Jim and Kim Haubenschild were attacked inside their home in Aurora. An intruder entered the residence during the night and struck the couple with a hammer. Both survived. The attack later became important to investigators because of its timing, location and similarity to the fatal crimes that followed.
The Murder of Patricia Smith
On January 10, 1984, Ewing entered the Lakewood townhouse of Patricia Louise Smith. Smith was a 50-year-old mother, grandmother and professional interior designer. She shared the residence with members of her family, although she was alone when she was attacked.
Ewing sexually assaulted Smith and struck her repeatedly with an auto-body hammer. Her injuries were fatal. The crime scene was extremely violent, but investigators initially had no suspect who could be conclusively connected to the murder. Biological evidence was collected and preserved, becoming essential many years later when improved DNA testing made it possible to identify Ewing.
Smith’s killing was investigated separately from the Bennett murders because it occurred in a different city and jurisdiction. Although detectives recognized similarities among the January attacks, forensic technology available in 1984 could not establish the connection that DNA evidence would eventually reveal.
The Bennett Family Murders
During the night of January 15–16, 1984, Ewing entered the home of Bruce and Debra Bennett in Aurora. The couple lived there with their daughters, seven-year-old Melissa and three-year-old Vanessa. Members of the family had gathered earlier on January 15, and relatives last saw them alive that evening.
Bruce and Debra failed to arrive at work the following morning and did not answer telephone calls. At approximately 10:00 a.m. on January 16, Bruce’s mother went to the house to investigate. She found the residence open and discovered Bruce near the bottom of the staircase. Police officers responding to the emergency call located Debra in the primary bedroom and the two children in another bedroom.
Bruce, Debra and Melissa were dead. Investigators determined that all three had suffered devastating blunt-force injuries. Bruce and Melissa had also received sharp-force wounds consistent with a knife. Melissa had been sexually assaulted. The violence inside the house was so extensive that the case became one of the most disturbing unsolved crimes in Colorado history.
Vanessa Bennett’s Survival
Three-year-old Vanessa Bennett was found alive but critically injured. She had suffered severe blows to her head and had also been sexually assaulted. Vanessa was taken to a hospital and survived despite injuries that could easily have been fatal.
Because she was so young and had experienced serious physical trauma, Vanessa could not provide investigators with the kind of detailed eyewitness account that might have immediately identified the attacker. Her survival nevertheless became a central part of the case. Decades later, she spoke publicly about the lifelong physical and emotional consequences of the attack and about the loss of her parents and sister.
Other Violent Crimes and Arrests
Later in January 1984, Ewing was arrested in Arizona after another violent incident. While being transported by law-enforcement officers in August 1984, he escaped from custody at a gas station in Henderson, Nevada. During the escape, he entered a nearby home and attacked a sleeping husband and wife with an axe handle. The couple survived, and Ewing was captured.
A Nevada jury convicted Ewing of offenses connected to the escape, home invasion and attempted killings. He received a sentence totaling more than a century in prison. At the time, Nevada officials did not know that he would later be linked to the four Colorado murders.
The DNA Breakthrough
For decades, detectives continued reviewing the Smith and Bennett cases. Evidence from the crime scenes had been retained, including biological material associated with the sexual assaults. As forensic science advanced, investigators were able to develop increasingly useful DNA profiles.
A major break came after Nevada expanded the collection and testing of DNA from prison inmates. Ewing’s DNA profile was entered into law-enforcement databases and compared with evidence from unsolved cases. In 2018, authorities announced that his DNA matched evidence connected to both the Bennett family crime scene and the murder of Patricia Smith.
The match connected crimes that had remained unresolved for approximately 34 years. Colorado prosecutors filed charges, and Ewing fought extradition before he was eventually transferred from Nevada to Colorado for trial.
Trial for the Bennett Murders
Ewing was tried in Arapahoe County for the attacks on the Bennett family. Prosecutors presented DNA evidence along with testimony about the crime scene, the surviving victim, the forensic investigation and Ewing’s other violent conduct. The prosecution argued that the DNA evidence placed him inside the home and conclusively connected him to the sexual assaults and murders.
On August 6, 2021, a jury found Ewing guilty of murdering Bruce, Debra and Melissa Bennett. He was also convicted of attempted murder for the attack on Vanessa, as well as sexual assault, sexual assault of a child and burglary charges. On August 17, 2021, he received three consecutive life sentences for the murders. The sentencing rules in effect when the crimes were committed allowed the possibility of parole after the required minimum periods, but the consecutive sentences made his continued imprisonment effectively certain.
Trial for the Murder of Patricia Smith
Ewing was later tried separately in Jefferson County for the murder of Patricia Smith. Prosecutors relied heavily on the preserved DNA evidence, supported by the similarities between Smith’s killing and Ewing’s other hammer attacks.
On April 7, 2022, the jury convicted Ewing of first-degree murder after deliberation and two forms of felony murder connected to robbery and sexual assault. On April 12, 2022, he was sentenced to another life term. The conviction officially resolved a murder that had haunted Smith’s family and Lakewood investigators since January 1984.
Legacy of the Case
The investigation of Alex Christopher Ewing demonstrates how carefully preserved evidence and advances in DNA technology can solve crimes long after the original investigations have gone cold. In 1984, detectives could document the similarities among the attacks, but they lacked the scientific tools needed to identify the unknown offender. More than three decades later, the same biological evidence provided the connection prosecutors needed.
Ewing was ultimately convicted of four murders and numerous additional violent offenses. His crimes destroyed two families, left several survivors with lasting injuries and caused fear throughout the Denver metropolitan area. The convictions brought legal accountability, but they could not restore the lives of Patricia Smith, Bruce Bennett, Debra Bennett or Melissa Bennett, nor erase the suffering experienced by Vanessa Bennett and the other survivors.
