How a melted Almond Joy candy bar triggered horrific sequence of events that ended with cop killing Florida man, 19

A Florida man was killed by cops after he reversed into his grandmother in a blind rage after she left an Almond Joy candy bar to melt on top of his computer.

Henry Maynard, from Polk County, got into an argument with her after she bought him chocolate while he was asleep.

He woke up, saw it had melted on his computer and 'went into a rage' before running nearly a mile to his parents' house where he picked up a bag and took a car.

Maynard called 911 to say he was about to commit a crime and was confronted by a Polk County deputy and his worried family.

He reversed into his 81-year-old grandmother and rammed into sheriff’s deputy Christian Quattlebaum's car before trying to enter it and he was shot dead by the deputy.

The elderly woman suffered a broken arm and was taken to a nearby hospital.

Maynard, who did not have a driving license, took a car from his parents' house which was unregistered and called 911.

'He tells the operator he’s about to commit a crime and he needs to be able to escape,' Sheriff Grady Judd said.

His grandmother called his parents and said 'he’s here in the car and he’s in a rage', according to the Sheriff.

The teenager's mother, who worked as a Polk County detention deputy for 10 years, and his father, a nurse, made their way to the scene.

He was confronted by his family and Deputy Quattlebaum near Oakwood Estates in Winter Haven.

But Maynard reversed his car and knocked his grandmother over before accelerating into the sheriff deputy's car and tried to enter it.

'A neighbor said that this man jumped out of his vehicle in an absolute rage, like a madman, ran to the driver-side door of the deputy’s vehicle and started yanking on it ‘til it came open and started climbing into the vehicle,' Judd said.

'Our Deputy Quattlebaum is trying to get out of the passenger side of the car because he doesn’t know what this person’s doing.

'They just rammed his vehicle and is now trying to attack him.'

The sheriff's deputy pulled out his gun and shot Maynard during the chaotic scene.

The teenager's father tried to save his life with CPR but he was pronounced dead at the scene.

Quattlebaum, who has worked with the force for four and a half years, was treated for his injuries.

The incident is being investigated by the 10th Judicial Circuit’s Officer Involved Deadly Incident Task Force.
