Shannon Price, the ex-wife of late actor Gary Coleman, recently underwent a polygraph test concerning the circumstances of Coleman's fatal fall in 2010. Coleman, known for his role on the television series "Diff'rent Strokes," died after falling down the stairs at his Utah home, with his death officially ruled an accident. Price's polygraph results were widely reported as a failure, raising renewed questions about her potential involvement in the incident. Despite the test outcome, Price has maintained her innocence, stating she had no choice but to take Coleman off life support two days after his fall, in accordance with his living will that specified a 15-day limit on life support. The polygraph test and Price's explanations were featured in the A&E special "Lie Detector: Truth or Deception," which aired on July 10, 2025. Former FBI agents and others have expressed skepticism about Price's account, suggesting she may know more about Coleman's death than she has disclosed. The renewed scrutiny comes 15 years after Coleman's death and follows longstanding speculation about the circumstances surrounding the fatal fall.
