A man convicted of murdering an Opp woman in 1991 is now facing a federal sex abuse charge in Coffee County.

Calvin Nelson, 49, was convicted in 1992 of the stabbing death of Jennifer Lacey Larkins of Hardin Street. Jurors believed that Nelson self-inflicted stab wounds as an attempt to cover his involvement in Larkins’ murder. It took jurors two hours to convict him. He was sentenced to life in prison; however, Nelson was paroled in 2005, after serving nearly 13 years in prison.

Nelson’s newest charge is the result of an alleged incident that occurred while he was employed as a contract worker at Lister Army Hospital, which is located at Ft. Rucker.

Cynthia Dillard, executive director of the Alabama Board of Pardon and Parole, said Nelson is now charged with abusive sexual contact, a federal offense that stemmed from an incident with an adult female.

Nelson was arrested by U.S. Marshals on Jan. 13 and booked into the Coffee County Jail on a violation of parole charge. He is being held without bond.
