Michael Todd Fulwood,

Michael Todd Fulwood, 36, pleaded guilty Thursday in U.S. District Court in Oxford to a felony charge of conspiracy to commit witness tampering, authorities said.
The investigation dates to March 8, 2003, when Patrolman Adam McHann allegedly violated a teenager's civil rights by ordering a police dog to bite and maul him for no reason.
Assistant Police Chief Scott Gentry and McHann are scheduled for trial Feb. 11.
McHann is charged with depravation of civil rights.
Federal prosecutors say Fulwood and Gentry were not directly involved in the attack. However, in the weeks following the incident, Gentry and Fulwood allegedly tried to cover up McHann's purported wrongdoing, telling a concerned fellow officer that filing a complaint might end his law enforcement career, according to the indictment.
As part of the plea agreement, Fulwood admitted Thursday in court that he and Gentry conspired to pressure the officer not to report the incident, according to prosecutors.
Fulwood and Gentry also lied to an FBI agent about their role in allegedly trying to cover up the incident, authorities said.
According to the indictment, Gentry acknowledged in a taped conversation that McHann's use of force was illegal but pressured him to "keep it quiet."
Fulwood reinforced Gentry's instructions by saying that there is a "silent code" among officers, according to court documents.
The three officers have been relieved of duties with pay from the Olive Branch Police Department.
If convicted, McHann could be sentenced to a maximum 10 years in prison and/or $250,000 in fines; and Gentry and Fulwood could be sentenced to a maximum 20 years in prison and/or $750,000 in fines each.
