Dr. Randeep Mann
"Today's superseding indictment charges Randeep Mann a Russellville doctor, who had various disciplinary matters with before the state medical board, with two counts related to that bombing," says U.S. attorney Jane Duke.
Former Russellville doctor Randeep Mann has been accused of creating a homemade bomb in early 2009.
"Before Dr. Pierce could get into his vehicle, he was injured by the detonation of an explosive device," says Duke.
This bomb left Dr. Trent Pierce of West Memphis without his left eye and severe burns. Federal investigators say it was all in retaliation.
In 2003, Mann's authority to prescribe medications was suspended by the medical board, then revoked in 2006. Pierce headed the board.
These charges follow a slew of others in 2009, after federal agents found two grenade launchers in Mann's Pope County home along with more than 100 automatic machine guns, some of which were not registered.
"A lot of great work went into this. We utilized every expertise we had. Our laboratory, our firearm experts, our explosive experts," says Phil Durham of the Bureau of Alcohol, Tobacco and Firearms.
Authorities say there has been a motion to severance filed; that would ultimately separate Mann's 2009 charges from that of his wife, Sangeeta Mann.
His wife's charges also stem from the 2009 weapons case which include obstruction of justice and perjury before a grand jury.
At this time, Mann is being held by federal agents without bond and if convicted, could face up to life in prison.
Pierce is still recovering and has attended at least one medical board meeting since the blast.
Both the Manns face a judge in March. Randeep Mann has plead not guilty.
