Relatives of an Arizona father who has been missing for months say that they believe he was murdered. Kyle Smith was last heard from on July 14, 2025, while talking to his wife on his cell phone. His family later told the Arizona Republic that his phone was found in front of Country Gables Park, while Smith, 26, has not yet been located. Smith's mother, Kristen Cline, told the Republic on Tuesday, March 10, that detectives informed her that the son has been linked as the victim in what appeared to be a murder scene that took place at the park.
