In a plea agreement, Coleman was sentenced to time served, which was five months, and six months' home confinement under electronic monitoring.Conspiracy theories alleging that the federal convictions of Lester Coleman were an effort to silence him and to hide the truth about Pan Am Flight 103 circulated around the internet.
