In 1992 she was convicted of only one of the seven murders and sentenced to death.
Wuornos was charged with the first-degree murder of Richard Mallory, armed robbery with a firearm or deadly weapon, and possession of a firearm by a convicted felon.

The 51-year-old owner of a Clearwater electronics-repair business used to close up shop abruptly and disappear for a few days at a time on binges of heavy drinking and perverted sex. It was his secret life.
With no male friends, he was an extremely secretive, paranoid loner. It has been claimed that Mallory changed the locks to his apartment many times in the three years before his death. It is also said that he had been involved with an ambassador’s wife; he certainly appeared paranoid whether this woman was mentioned.
He thought he was being followed and wanted to have plastic surgery to get his nose altered, presumably so he wouldn’t be recognized. He was a strange fellow indeed, this Richard Mallory.
He employed staff only long enough to clear the backlog of work that occurred during his disappearances, and let his workers go once his repair orders were up to date. Perhaps this was a prudent, financially astute move for a man whose credit cards were no longer valid, a man who needed every dime for something far more appealing…
Unbeknown to the jury, the only constants in Mallory’s life – apart from his unexplained absences from work – were heavy alcohol consumption and an insatiable desire for sex. He used the services of hookers, visited strip joints and was seriously into hardcore pornography. He also used drugs. Apart from a recent girlfriend, no one – including the jury at Lee’s trial – was aware that he had served the better part of ten years in the Maryland State Mental Institution for an attempted rape.
Mallory was a private man, and an enigma to everybody. Living alone in a multi-family apartment complex called The Oaks, few people came to know him on account of his erratic lifestyle; at his television-and video-repair shop, Mallory Electronics in Palm Harbour, his absences were frequent and unexplained.
With a population of just under 60,000, one might have thought that Mallory’s business would have done a roaring trade in the Clearwater area. He knew his stuff, turned out quality repairs and didn’t charge his customers a fortune. However, he had squandered all of his firm’s profits on deviant sex. He was in serious financial straits. Bankruptcy loomed over Richard Mallory and his company. To kick off with, he owed serious money.
The sums included $4,000 in rent arrears for the business, and a small packet on his apartment. The credit card companies had closed his accounts. Business transactions were now all in cash. He was due to be swept up, closed down and evicted by his landlords. His business affairs were due to be audited by the Inland Revenue Service. He had stalled the inspectors for too long, and pressure was mounting. The result was that Mallory had a good many problems on his mind.
Some would say he was a good-looking man with his full head of dark hair combed back from a high forehead. Standing at just less than six feet tall, the neatly mustachioed Mallory surveyed the world through hazel eyes behind wire-rimmed glasses. He cut a trim figure, tipping the scales at just less than 170 pounds, and he thought of himself as 51 years young. Five times divorced and recently separated from an entirely decent girlfriend called Jackie Davis, Mallory had always been drawn to the opposite sex and seedy exchanges. He loved to party in the debauched sense, and was a regular visitor to the kinds of adult-entertainment establishments dedicated to catering to pleasures of the flesh.
Mallory liked the way women looked, the way they smelled and moved. He liked the way he felt when he was with them – powerful, controlling, sensuous. He liked power over women; he liked to abuse them, to tie them up, handcuff them, bite them and knock them around. To him, street women and those who flaunted their bodies were up for ill treatment.
When Richard Mallory didn’t show up to open his shop on Monday, 3 December 1989, his staff and clients didn’t think much of it. As far as friends went, there was no one close enough to him to notice he was gone. Frankly, no one even cared. It wasn’t until the cops turned up at his business saying they had found his abandoned Cadillac outside Daytona that anyone knew anything was amiss.
No one ‘gave a rat’s ass’, as one officer dryly observed. The best beach in Florida!

A perfect destination for honeymooners and couples! Vacation values that won’t bust your budget! So scream the tourist brochures. But Daytona is no different to many cities: along the star-spangled sidewalks, lined with laundromats, strip joints and seedy hotels, Joe Public can get his ‘round the world’ (everything) for 80 bucks, or a straight ‘ho’s strip’ (where the hooker strips for oral only) for 20.
Richard was a sufficiently regular customer at the topless bars in the Tampa, Clearwater and Daytona areas that the strippers, go-go dancers and hookers mostly knew him by sight, if not by name. When he latched on to them, he was like a rigged fruit machine – guaranteed to pay out nearly every time.
Mallory told Aileen he knew girls in topless bars and bragged he would pay $2,000 per photo session. He talked about politics, religion and that his electronics store was going through troubled times.
Kimberly Guy had made a previous complaint to police that, in addition to having an affinity for prostitution and brutal sex, Mallory was equally interested in masochistic sex and that ‘he frequently travelled with a pair of handcuffs in his briefcase’.

Notes and phone numbers in the dead man’s apartment led investigators to two dancers at local strip clubs, Chastity Marcus and Kimberly Guy, and Doug Lambert, Chastity’s boyfriend.
Initial suspicion revolved around Chastity who was described as ‘as hot as a firecracker’ by the manager of the strip joint where she worked. She told the cops all about Mallory and his sick perversions. She introduced them to other girls who had been abused by this sexual pervert. Even Mallory’s former girlfriend Jackie Davis told officers that he had been incarcerated for sex offenses for ten years. But the cops slammed them all down and the case went cold.
By the middle of May 1990, the murder of Richard Mallory had been all but forgotten by the Volusia County Sheriff’s Department. There was, seemingly, no reason to believe it was anything other than an isolated homicide.


Mallory’s sister in Texas and his brother in New Jersey wanted nothing to do with Richard’s business. An individual named Mr. Townley took over the repair equipment that had been dumped, moved the shop several doors from the original site, and Mallory Electronics became Johnny’s TV & VCR of Palm Harbor. Jackie Davis took charge of Mallory’s cremation and scattered his ashes in nearby woodland.

Tyria knew about the murder of Richard Mallory because Lee had told her. In fact, she told her the very same day Lee had killed the man. Lee gave Tyria a scarf and jacket belonging to Mallory – it had ‘Richard’ printed inside the jacket collar – and she showed her a camera, a radar detector and tool box which had mysteriously come into her possession. And, if all of this was not sufficient to raise Tyria’s suspicions from non-belief to that of shock, she could have hardly failed to notice the blood-spattered car seat while she was driving round in Mallory’s car for an hour.
