A licensed practical nurse from Ansonia who is accused of murdering an Eastern Connecticut State University student has lost his nursing license in an unrelated case involving a fight he had with a visitor in a patient’s home. The Board of Examiners for Nursing voted Wednesday to revoke the license of Jermaine V. Richards, 34, after holding a hearing. Richards did not attend the hearing because he is being held on a $500,000 bond at Northern Correctional Institution in Somers on a charge that he murdered his is ex-girlfriend, Alyssiah Wiley, 20, of West Haven in 2013. After an extensive search, her dismembered body was found in Trumbull in May 2013, less than two miles from Richards’ home, the Connecticut Post has reported. Richards, who denied the nursing charges in a letter to the state Department of Public Health in December, was not represented by a lawyer at the hearing.
