Jason & Ken MacLennan Case [Shoot to Thrill] Forensic File Case Study: Forensic Approach to Ken MacLennan Death

Two students ruined their life: one to take revenge and the second for $1000. One got life imprisonment and the other got 30 years in prison. They planned the incident but failed as forensic investigations and evidences came into play.

This is a case study from the Forensic Files cases of Shoot to Thrill, Season 13, Episode 3 of Ken MacLennan’s murder.

Summary of Shoot to Thrill: The Murder of Ken MacLennan: Forensic File

On January 14, 2003, around midnight, Ken MacLennan (53), a vice president at Creating Memories was found dead on the hardwood floor of his home. His son Jason Alexander MacLennan (17), was the first that called 911 and reported the incident.

Jason told the investigators that he arrived home around midnight, took a shower, and was going into the kitchen to eat something when he discovered her father.

The scene at first appeared like a robbery since Kenneth’s wallet, watch, some cash (national and international currency), and a few IDs were missing. However later forensic investigation showed Ken was shot by four different types of ammunition that pointed toward an intentional killing.

Recovery of forensic evidence such as 3 sets of footprints, a shell casing that was accidentally left by the culprits, DNA evidence from recovered clothes, and weapon of crime helped the investigators to solve the well-planned murder involving young teenagers.

Let’s take a deeper look at the case

Who were Ken MacLennan and His Family?

1. Ken MacLennan: Ken MacLennan was born on August 28, 1949, and a widower. He moved to the USA from Canada with his wife and 17-year-old son Jason. Ken secured a high-end management job and was a vice president at a photo album company called Creative Memories.

2. Dead wife: Betty Irene Relf was Ken MacLennan’s wife. She was suffering from breast cancer and had two mastectomies (breast tissue removal surgery) and died on July 13, 1999. The family was living in Florida during her treatment but moved to Canada temporarily to allow Betty to be close to her family during her final time.

3. Fiancé: Laurence Morand (Forensic Files referred to her by the pseudonym “Alessandra.”), a Swiss businesswoman, she was in courtship at the time of Kenneth’s death. Ken and Laurence started dating in 1999 shortly after Betty’s death and she eventually moved into the MacLennans’ house. They were also planning their wedding.

Laurence Morand was also a beneficiary of $100,000 from Kenneth’s Creative Memories life insurance policy. She was initially listed as a suspect but as she was in Switzerland at the time of the shooting, so police ruled her out.

4. Son: Jason MacLennan was the only child of Ken and Betty born in Canada on Feb 22, 1985. The MacLennan family lived in Florida for most of Jason’s childhood. He was a student at St. Cloud Tech High School. Jason had a troubled relationship with his father.

Net worth: Kenneth had about $1.4 million of insurance and assets.

What Happened to Ken McLennan? How Did He Die?

On January 14, 2003, Jason and Matt waited for Ken to come home from the business trip and fall asleep.

Around midnight, Moeller walked to the front door and rang the doorbell. Ken came to open the door and walked toward the stairway where Jason was standing with the rifle.

Jason shot his father seven times. Matt picked six shell casings (and forget one) and Jason put on a glove and disturbed the house to make it look like a robbery.

After that, Jason changed clothes and both drove to the Matt family’s property and disposed of bloodied clothes and belongings they stole. Matt kept his rifle in his car. Jason went home and took a shower while Matt drove to his home.

  • Wounds are present on Temple, forehead, chest, throat, hand, and back. One gunshot had gone through Ken’s hand (he might have tried to stop the killer).

Test slugs (obtained from firing in a 600-gallon water tank) were compared to the slugs recovered from inside Ken’s body. The two of slugs didn’t match due to a tempered barrel.

3. Instrumental Analysis of GSR

Instrumental analysis of GSR particles is majorly done by Scanning Electron Microscopes with Energy Dispersive X-ray Analysis (SEM-EDX). The test shows the recovered hand gloves positively indicated the use of four different types of ammunition.

4. Shoe Prints

Black dyed impressions from shoes (like taking fingerprints) were obtained on the transparent sheet. These when then compared with life-size (1:1) photographs of the shoe print impressions by superimposition method.

  • Two shoeprints were matched with the shoes of Jason and Matt.
  • The third print matched the Lugz shoe recovered from Matt’s basement.

5. SoleMate® FPX

How Firearm Recovered from Matt Muller Examined?

Part 1: Why it is hard to do a ballistic examination of the recovery shotgun from Matt Moeller?

The intentional damage to the barrel of the rifle made it difficult to do the ballistic examination. Comparison of Land and groove marks gave negative results due to the same reason. Matt used Allen wrench in the barrel of the gun to alter it.

  1. Firing pin marks: side by side comparison of firing pin marks with the help of a comparison microscope helped in positive identification.
  2. DNA from inside of barrel: One of the shot were on Ken’s right hand. It seems that he tried to grab the weapon in self-defense when the shot was fired. This results in blood spatters inside the muzzle of the barrel. A test was done and it gave a positive identification for Kenneth.
