A 43-year-old former Road Rules star was found dead at his Phoenixville, Pennsylvania, home last Thursday, the local coroner's office confirms to Us. Brian Lancaster, who competed on the seventh season of the MTV reality show in 1999—Road Rules: Latin America—had a history of arrhythmia, his family tells TMZ, and they believe heart failure killed him. They say neither drugs nor alcohol were involved in his death, and no substances were found in his home. Per an obituary, he had a master's degree in elementary education and had worked as an advertising account manager, telecommunications project manager, special education teacher, and bartender. He leaves behind a fiancee. (More MTV stories.)
