Attorney Robert Simels was convicted Thursday of 12 felony counts — including bribery of a witness, attempted witness tampering and conspiracy to commit witness tampering — stemming from his efforts to prevent potential witnesses from testifying against his client, Guyanese drug-smuggler Shaheed “Roger” Khan.

Simels was acquitted of only the least-serious charge against him, making a false statement to a corrections officer in order to visit an inmate.
