A woman has told of how she discovered her friend was a convicted murderer - and claims she was "next on his list".
Nedra Calloway, from Richmond, California, told of her encounter with convicted murderer Kevin Sterling Jones who killed two other women.
She claims to have found out that she was "next" on his hit list from recordings shared with the police by an informant.
In a TikTok post, Nedra claims to have survived the convicted killer who allegedly bragged about his "sick twisted plans" to end her life.
The recordings also included Jones's admissions to killing 22-year-old college student Jamie Williams in Oakland, California, in 1999, and his second victim, 16-year-old girl, Sharonda Parker, in Napa County.
In the TikTok, Nedra, now 51, explains how she met Jones, who her friends nicknamed "weirdo", through another pal only referred to as T in 2000, when she was 29.
The postal worker said: "When I first met weirdo [Jones] he wasn't T's boyfriend yet. T and I had seen him several times hanging around the adult store that [she] managed at the time but neither of us knew him.
"T and I had nicknamed him 'weirdo' because he was very quiet, never saying a word, just staring at the adult videos playing on the TV in the store.
"I never saw him buy anything, he just hung around the store. We felt like something was off."
A friendship blossomed between the trio but things soon turned sinister.
Nedra said: "Weirdo [Jones] was arrested because a young lady in our apartment complex accused him of peering through her windows, and leaving sex tapes on her doorstep."
Convinced there had been a mistake and taken in by the charismatic killer, Nedra made the decision to testify to Jones' character, a decision she now regrets.
The charges against him were dropped.
She said: "Initially on seeing him, I thought he was weird and strange, but the minute he opened his mouth to introduce himself he seemed like a normal guy.
"I remember thinking oh 'weirdo' may not be so weird after all. He had us all fooled. He had an amazing sense of humour, [was] fun to be around and could adapt to any situation or converse with anyone at any age.
"I never thought he could do such things. Had I known I wouldn't have testified in his favour."
Sadly, this would not be Nedra's last encounter with the killer.
After a bizarre visit where Jones seemed visibly panicked and allegedly told Nedra he had been at the police station all day, the pair lost touch.
However, they reconnected in late 2002, when Nedra claims he was hostile and "insisted" that she visit him.
She said: "He said if I was really his friend I would. It really scared me and I hung up the phone."
Nedra listened to her "gut" and did not visit Jones that night - a decision that may have saved her life.
Days later, she received a call from a Napa County Detective and was finally given an insight into the killer's dark past.
She went in to speak to the detective and learned the chilling truth about her 'friend' - he was currently in prison after attempting to rob a beauty salon.
Nedra said: "The detective told me that [Jones had] been peering in my windows. He asked me if I knew that Kevin had already served 13 years in prison for violent sexual crimes. I began to shake, I had no idea.
"He then played the recording where I heard in Kevin's voice say to the informant that I was next.
"I was absolutely horrified! I was so upset I had trouble breathing and was totally inconsolable. He pretended to be friendly to gain my trust. It was all a part of his sick, twisted plan."
Now 51, Nedra is shared her story to encourage others to trust their gut and do background checks which were not available when she was 29.
She added: "The experience taught me to follow my first mind, when my 'spidey senses' start to tingle pay attention.
"Trust your gut. We have a whole lot more resources we can tap into than we did 20 years ago. Background checks are free or very close to it.
"Stop collecting red flags! They are red for a reason."
