EXCLUSIVEBizarre TikTok clip alleged Daisy Hill hit-and-run murder accused shared before young mum Kiesha Thompson was struck walking home from daycare

EXCLUSIVE

Horrified witnesses have relived the haunting sound of a young mum allegedly being mown down in a hit-and-run by her ex-partner's new girlfriend - as details emerge of a viral sex act meme the accused killer posted on the day of the alleged murder. 

Kiesha Thompson, 23, was allegedly struck by a Toyota LandCruiser Prado in Daisy Hill, in south Brisbane, on Friday morning as she walked home along a footpath after dropping her daughter at daycare. 

A local resident, who wished to remain anonymous, said he was in his yard when he heard a loud 'thud' then the sound of a car [allegedly] speeding off. 

He rushed outside, where he saw Ms Thompson lying on the road and his neighbour, a tradesman, frantically giving Ms Thompson CPR. Another neighbour, a nurse, also raced over to give the young mother first aid. 

'She had a bump on her head, but she didn’t actually look that injured.. there wasn't that much blood,’ he told Daily Mail Australia. 

‘The ambulance crews were here pretty soon after that and took her to hospital.’ 

The man said it appeared Ms Thompson had been sent flying through the air before landing about 20m away from a spot where dark marks remained on the gutter.

'I hadn't see her around here before, but it has rattled the local community,' said the neighbour. 

‘It is very sad.' 

Despite the efforts of first responders and paramedics, Ms Thompson later died in hospital. 

Ms Thompson's ex-partner Tyler Scott William James, 27, and Larissa Rita Mae-Leigh Sant, 24, have been charged with domestic violence murder and are in custody while their matters remain before the courts. 

Sant’s social media posts offer insight into a new whirlwind romance in the weeks leading up to the tragedy.

Just five months ago, Sant shared a video on TikTok reflecting on how she would be single for Valentine’s Day. 

However, just four days later, she revealed she was smitten over a new person in her life.

‘Just when I thought I was in my I don’t need a man era…. Then you came along and now I’m smiling at my phone like a little girl with a crush,’ she wrote on February 18.

Over the next few months, she continued to share snippets about her blossoming romance, revealing in March her relationship status was single but '(fwb)', an abbreviation for a casual sexual relationship, 'friends with benefits'.

By May, she announced - while lip syncing to a song about one day finding love - that she had ‘found him.’ 

On July 10, less than two weeks before the alleged murder, she exclaimed that she had fallen in love, writing: ‘Falling/fell now forever stuck.’ 

Police will allege Sant spent an ‘extended amount of time’ driving around the Daisy Hill area in the lead up to the alleged attack. 

Daily Mail Australia can reveal Sant - a young mother of three boys aged between three and five - continued to post on TikTok on the day of the alleged murder.

In one post, she made a comment about the newly-formed viral Tiktok meme, Huak Tuah, a term which refers to spitting during a sex act.

In another, she commented on a post about liking a song.

Five days on from the tragedy, plain clothes detectives could be seen visiting the homes of local residents as they continue to canvass the area for CCTV footage.

Officers also remained stationed outside Sant’s home in Goodna, some 30km away, with neighbours revealing police have not left the premises since Sant was arrested on Saturday.

While Sant was arrested in nearby Yamanto, one neighbour said officers had towed a car from the Goodna residence over the weekend and sniffer dogs were brought in to assist with the house raid. 

One woman, who wished to remain anonymous, said she hadn’t seen much of Sant since she moved into the property two years ago, although she often heard her three sons playing outside in the backyard. 

‘The boys would be outside, climbing on a retaining wall. Sometimes you would hear them screaming “mum” for around 15 minutes, trying to get her attention, but I would never see her come out,’ she said. 

‘Sometimes they were naked in the yard too. The boys were here on Saturday, before leaving in an Uber.’ 

Children’s toys, including a trampoline, bikes and trucks, could be seen scattered around the semi-overgrown backyard on Wednesday. 

Meanwhile, officers were similarly seen standing guard at James’ Acacia Ridge home on Tuesday evening as they continue to investigate the circumstances surrounding Ms Thompson’s death. 

Two plumbers arrived at the home and spent several hours fixing a leak after being contacted by police. 

Daily Mail Australia understands Ms Thompson previously lived at that address with James before their relationship ended several months ago. 

One local said they had seen James around the neighbourhood and women sitting on the front porch of the home, but he had never spoken to them. 

‘Most people keep to themselves around here,’ he said. 'But what [allegedly] happened is really sad.'

Sant and James are next due before Beenleigh Magistrates Court on July 31, where their cases will next be heard together as a committal trial mention.
