Book of Premeditation

The prosecution at his trial dubbed the handwritten journal found in Guy Jr.'s backpack the "book of premeditation", as it contained detailed notes outlining his intent to murder and destroy the remains of his parents.^[12]

One page includes the following:^[13]

                                                                   

• Get killing knives - quiet - multiple         *get carving knives to make small pieces
• Get sledgehammer - crush bones
• Bring blender and food grinder - grind meat
• get bleach - denature proteins
• get plastic bin for denaturation process
• does not matter where they're killed

just get rid of bloody spots to prevent

evidence of time of death (not the mattress or couches)

• get rid of bodies inside house - their and my DNA already there
• open up doggie door to provide entryway        he needs to be blamed, not intruder
• flush chunks down toilet (not garbage disposal)
• get plastic sheeting for disposal process
• get hollow point bullets just in case will be seen buying bullets; just use computer room gun →

      check to make sure there are bullets (last resort

• He's not alive to claim her half of the insurance money → all mine ($500,000)
• flood the house, covers up forensic evidence
• turn heater up as high as it goes → speeds decomposition.
• bleach reacts with luminol just like blood → douse area with bleach
• big sprayer
• lye
• trash compactor?

      Body gives times of death → alibi

• Don't have to get rid of body if there is no forensic evidence on the body.
• HIS FINGERPRINTS AND DNA

Surveillance footage

Guy Jr. was caught on several surveillance cameras buying the supplies he would later use to murder and try to dissolve his parents.^[14] He used cash for every transaction, and self-checkout most of the time. He bought supplies for the murder as early as November 7, purchasing several items at an Ace Hardware in Napoleonville, including muriatic acid and food-grade hydrogen peroxide. On November 18 at Home Depot, cameras record him buying the bleach sprayer, extension cords, and a timer.^[3] At Academy Sports on November 19, he is seen buying a knife. On November 21, cameras capture Guy Jr. at a Knoxville Walmart buying a plastic blue tote large enough for the dismembered bodies to dissolve in.^[15]

Lisa Guy was also seen on surveillance footage shortly before her murder, buying items at Walmart at approximately 12:15 PM.^[16]

Joel Guy Sr.

On November 26, Guy Jr. attacked and killed his father with a knife in a second floor exercise room while his mother was out shopping for groceries at Walmart. The scene showed evidence of a struggle, with torn blinds, blood on the wall and corner, and an overturned Bowflex machine.^[16]

Lisa Guy

Upon arriving home, Lisa Guy entered through the front door, dropped the groceries on the floor of the foyer,^[17] proceeded upstairs, was attacked, then killed with a knife.^[16] Nine of her ribs were severed.^[18]

Dismemberment

Guy Sr.'s hands were removed at the wrists and left nearby on the exercise room floor. Lisa's head was removed, carried downstairs, placed in a pot on the stove and heated. At trial, the forensic examiner testified the head was not just severed but broken off with force. Both victims also had their arms and legs disarticulated, Guy Sr. at the waist and Lisa at the knees, and their limbs and torsos were placed in a bin full of chemicals to dissolve. Each body had a large gash inflicted after death so that the chemicals would more quickly seep into the body's main cavity.^[18]

Cuts to perpetrator

In the assault on his father, Guy Jr. sustained several cuts to his hands, including a deep cut to his left thumb. At approximately 3:30 PM, Guy Jr. was seen in Walmart's first aid section, obtaining bandages and ointment for the wounds to his hands. He also purchased isopropyl alcohol and hydrogen peroxide.^[11]

On Sunday, Guy Jr. drove back to Baton Rouge to have his wounds treated at the student clinic.^[19]

Welfare check

At first, Knox County officers Steven Ballard and Jeremy McCord and others found a seemingly empty house on Goldenview Lane. The property was for sale, yet there was no real-estate lock on the front door. They soon discovered the back door doorknob had been removed and installed on the front door. Through the front door, they could see groceries on the floor, including perishable items such as bacon, sausage and ice cream.^[20] Through the hole left by the missing back doorknob, they could sense heat and a strange smell emanating from the house, and from another angle, they could see the groceries. An officer used a garage door opener in one of the Guys' cars to gain access to the house.^[20]

They first discovered a table with the Guys' wallets and a sledgehammer on top, and then another with long guns. Downstairs, the stove was on and the contents of a pot were boiling. At the bottom of the stairs were the grocery items seen earlier. They ascended the stairs, hearing an intermittently barking dog. They looked down a hallway, saw Joel Guy Sr.'s severed hands on the floor, and discovered the dismembered corpses in solution in a bathroom.^[20]

Among other items investigators found upstairs were sewer line cleaner, a bag of baking soda, drain cleaner, hydrochloric acid, drain opener, lye, hydrogen peroxide, bleach and a bleach sprayer.^[21] Investigators also discovered a note in an open suitcase with the name and an address of a Louisiana Ace Hardware store, along with a notation about sewer line cleaner.^[21]

The toxins required bio-hazard equipment for removal by the KCSO Hazmat Team. Due to the volume of evidence found, KCSO's Forensics Unit worked throughout Monday night and into the following day processing the crime scene.^[11]

Apprehension of suspect

The FBI, Knox County Sheriff's Office and East Baton Rouge Sheriff's Office placed Guy Jr. under surveillance for a few days and apprehended him on Tuesday, 29 November as he was entering his 2006 Hyundai Sonata in the Nicholson Drive apartment complex parking lot in Baton Rouge.^[22]

A meat grinder was discovered in the trunk of Guy Jr.'s car.
