The Sarasota County Sheriff's Office is asking for help locating missing 9-week-old Chance Walsh, who hasn't been seen in a month, PEOPLE has learned.
On Sunday, the baby boy's grandmother called authorities to report that she hadn't seen her grandson since Sept. 9 and was concerned about his welfare after his parents told her that they'd been in a car crash in South Carolina, the sheriff's office wrote in a news release.
Also, the boy's parents, Kristen Bury and Joseph Walsh, had allegedly told relatives contradictory stories to explain his absence, "including that the child was unharmed, that he died in the crash and that they gave him to a woman at a hotel in Georgia," the release states.
Investigators traced Bury and Walsh's movements over the past month and said they learned that there was not a baby with them at the time of the car crash, nor was there a child with them when they stayed at an Augusta, Georgia, hotel. However, the release states that a "woman staying at the hotel reported that Kristen tried to sell baby clothes to her and that Kristen told her the baby had died three weeks earlier.
