My daughter was strangled to death. Cops say an online market sale went wrong but I think it's more sinister

A grief-riddled Nevada mother has revealed chilling theories behind her 24-year-old daughter's unsolved murder.

Kimberly Briggs, 53, is still looking for answers eight years after her only daughter, Brittney Briggs, 24, was found beaten and strangled to death inside of her Las Vegas home while her three-year-old daughter Nadine was ‘asleep’ in another room.

Kimberly has since conjured a myriad of theories as to what happened to her daughter on the night of February 9, 2017, suspecting local law enforcement could have been more thorough in their investigation.

Speaking of her daughter’s investigation, Kimberly said: ‘I’m sure there had to have been DNA or something under her nails because you don’t just strangle a person without them fighting back. There had to be something that [police] could have used, something they could have looked further into.’

The shattered mother believes her daughter’s killer could have been someone she knew.

She revealed that the family discovered strange messages from a man who seemingly posted on Facebook details about Brittney's death before they were revealed by cops.

‘There are so many pieces that they never seem to be concerned with,’ the distraught mother told the DailyMail.com.

The distraught mother has since hatched other theories, her daughter, a recently hired tax preparer for Universal Tax, had just begun dating a man in the weeks leading up to her death.

‘There was her new boyfriend. She had only been with him probably two to three weeks,’ Kimberly said.

Yet, when Kimberly probed detectives, she claims they brushed her suspicions off.

‘The detective was saying “Oh, he’s really broken up. He wants to know if he can plan the funeral,”’ she recalled, ‘What!? NO!’ she replied, appalled at the suggestion.

She then suggested a third scenario, mentioning a member of Brittney’s church.

‘There was one creepy guy that she knew from church that struck me as odd,’ she said.

After sifting through her daughter’s Facebook and other social media pages she discovered an eerie post he shared the morning Brittney's body was found.

‘About 6.30am the morning her body was found, he had posted on Facebook about how one of his best friends had been strangled,’ she said.

‘But that information wasn’t even put out. That information wasn’t even public, we didn’t even know at the time. And her autopsy was not done until the next day, on Sunday afternoon.’

Continuing to put her mind to the test, theorizing all types of scenarios about what may have happened on that fateful night, Kimberly recalled another guy Brittney had gone out with years prior.

‘Another guy she had gone out with a handful of years prior, you know, on one date, he kind of struck me as the stalker type,’ she said.

‘I didn’t really think he was capable of all that, but to me he struck me as a little slow … something was definitely off. Creepy, but harmless I guess is what I would call it. Your mind goes all over the place when you’re really trying to think about every last thing that COULD have happened.’

Him too, Kimberly felt detectives could have paid a closer look into.

‘When I told that to the detective, all I got was “He has an alternative lifestyle” and I thought “I don’t know what that means and I don’t even care” I just want answers.’

She had also recalled her granddaughter's disturbing statement to the police. Though only three-years-old at the time, Nadine told police there was someone in her room covering her head with a blanket the night her mother died. 

'She told us stories about somebody being in her room that night telling her to keep the covers over her head and be quiet. Her explanation leads me to believe that there are two people involved,' Kimberly theorized.

'It is heartbreaking when we would hear Nadine, how she would talk about how mommy looked… that she wouldn’t wake up.'

Over eight years have passed and the Briggs family continues to hope for answers to their daughter's incomprehensible death. 

The grieving family continues to speak out, advocating for justice for their beloved child, a young single mother who appeared to have just found her footing and was on a path to success.   

'From the beginning we felt like authorities were disinterested, writing us off like another "welfare case,"' Kimberly exclusively told the DailyMail.com.

‘You see stories about rich people and influencers get more attention, and that is really what I am feeling like … maybe if we had more money to hire an investigator, maybe if we lived in the ‘ritzier’ part of town, or if Brittney wasn’t on state aid, maybe her case would get more attention,’ she said.

‘Instead, I feel as though it was just written off like “Well that’s another welfare case, case closed.”’

The young mother was found dead inside her home on Spindrift Court near Lake Mead Boulevard and Mount Hood Street on the morning of February 10, 2017. 

She was discovered by a friend who had stopped over after not hearing from Brittney.

The friend arrived at her Las Vegas home, with kids in tow as Brittney was scheduled to babysit according to Kimberly, however once she arrived she found the door wide open. 

The house appeared to have been ransacked, with the culprits stealing Brittney's cell phone, debit and EBT cards. 

'I want to hold her,' Kimberly told KNTV in 2017. 'I just want to see her again.'

'Nadine is precious and doesn't deserve to have lost her mom. She just keeps talking about seeing her mommy face down on the couch,' Kimberly told the outlet. 

'I've never seen anything like this around here happen, not even really a break-in, so it's a shock to all of us,' James Bass, who lives next door to Briggs' home, told KNTV at the time. 

Las Vegas Metropolitan Police say they saw no signs of trauma when they found Brittney's body, but the coroner later discovered the 24-year-old had been strangled. 

According to the Clark County coroner, the woman had several hemorrhages around her neck.

Neighbors said Briggs moved in about four years prior to her death.

'Since I moved in 10 years ago, I feel safe with the neighbors and we're just all kind of creeped out by it,' Chery Hope, another neighbor told the outlet. 'So sad, she was too young. So sad.' 

Around the time Briggs moved into the home, she met Maria Cane. Cane would grow to become one of her closest friends and the godmother to her daughter.

'All kind of things are running through my mind right now and my heart just breaks for Nadine, for the baby, for my goddaughter,' Cane said.

Cane claimed she has no idea who might have killed Brittney, but that she was very talkative and friendly, even letting friends live with her.

'She started the online dating thing and... she was trusting with everybody and that was something I was working with her about,' Cane added.

LVMPD later concluded that Brittney, who often sold items online such as clothes, trinkets and other miscellaneous things, may have been victimized by one of her customers.

'We are unsure what the motive behind this senseless crime is,' Lieutenant Ray Spencer of the Las Vegas Metropolitan Police Department said in a statement.

'However, we learned that Brittney sold clothes, trinkets and other items online. Things the killer may have taken with them.'
