New unconfirmed social media allegations are casting fresh suspicion on those closest to Rebecca Kay Park, a 22-year-old pregnant woman who vanished from Boon Township, Michigan, on November 3, 2025. According to a TikTok post by true crime creator Matt Thibodeau, shocking claims have emerged that Park’s fiancé once had a romantic relationship with her mother, an allegation that, if true, adds a startling new layer to an already complex missing person investigation. “Dating and pregnant by her mother’s ex” @mattthibodeau Replying to @Matt Thibodeau Disturbing new details in RebeccaKayPark’s disappearance seem to indicate that foul play could be involved here! #foryou #fyp #truecrime #breakingnews ♬ original sound – Matt Thibodeau “This guy right here, Rich,” identified in other news reports as Rich or Richard Falor, Park’s fiancé and Park’s unborn baby’s father, “is actually the ex-boyfriend of her mother, Courtney. Yeah, you heard that right,” Thibodeau says in his post. Thibodeau says in the video, referring to Park’s mother, Courtney Bartholomew, and her daughter’s fiancé, Falor, “Rebecca, 22 years old, is dating and pregnant by her mother’s ex.” Thibodeau cites residents from the area where Park lived who say the relationship was an open secret in their small community. However, according to Thibodeau, some allege Falor did not initially realize Park was Bartholomew’s daughter. The changing vehicle description Authorities in Wexford County are intensifying their search for Rebecca Kay Park, a 22-year-old woman who was last seen about a week ago, getting into a dark-colored vehicle outside a relative’s home in Boon Township.Park, who is now approximately 39 weeks pregnant, has not…— UpNorthLive News (@upnorthlive) November 11, 2025 The TikTok video also highlights multiple inconsistencies in statements Bartholomew has allegedly given to police and people close to her daughter. According to Thibodeau, Bartholomew initially told investigators that Park was picked up by a “dark SUV down the street.” Then she changed the description to “a Chevy Impala right outside the driveway.” Later still, she could not identify the make or model, describing only a “dark-colored vehicle.” She also allegedly gave conflicting descriptions of her daughter’s clothing, first saying Park was wearing “a black zip-up jacket, black shirt, and black sweatpants,” before changing that to “a black coat, light blue jeans, gray shoes, and carrying a black bag.” In his TikTok post, Thibodeau also pointed to online backlash against Park’s mother, noting claims from Facebook users accusing her of “bullying” volunteers who have tried to raise money or offer rewards for information. “She’s the last person to see her daughter alive,” Thibodeau said. “Is that due to nerves, or is that due to her trying to cover something?” What happened to Rebecca Kay Park? So far, Thibodeau’s claims are unconfirmed allegations and should be treated as such. According to the official story, Sheriff Trent Taylor confirmed that Park was last seen at her mother’s home around 11:30 p.m. on November 3, 2025. Her mother said she watched Park leave in a dark-colored vehicle after saying she “had to go do something.” Authorities later discovered her cellphone abandoned on a rural two-track road nearby. Despite extensive searches involving K-9 units, drones, and community volunteers, there have been no confirmed sightings or significant leads aside from Park’s phones, recovered on a remote unpaved dirt road near her mother’s home. Investigators said Park, who was 39 weeks pregnant when she went missing, had about $2,000 in cash, and there has been no bank or phone activity since. Falor said a hospital told her earlier that day she had dilated and sent her home to wait for labor to progress naturally. Officials emphasize that she is considered a missing and endangered person, not a fugitive.Falor told UpNorthLive that her disappearance was out of character. “I tried to call her a few times… nothing, and it’s just not like her,” he said. Friends have described her as responsible and cautious, saying she rarely went anywhere alone. A $12,000 reward remains in place for information leading to Park’s safe return. As speculation grows online, investigators urge the public to rely on verified updates from law enforcement and to report any credible information directly to the Wexford County Sheriff’s Office or Central Dispatch at 231-779-9211.
