Johnathan ’Jody’ Shields, 29, was shot and killed beside 501 Morse Street NE in Washington, D.C., on Sunday, June 6, 1999, at approximately 3:04 a.m. The Metropolitan Police Department’s Violent Crimes Branch lists the killing as an unsolved homicide and is offering a reward of up to $25,000 for information leading to an arrest and conviction.

Shields had been involved in the city’s criminal underworld and, months before his death, became a cooperating witness in the investigation of Shaquita Bell’s 1996 disappearance. He told police he helped Michael Dickerson dispose of Bell’s body; Dickerson was later convicted in that case. Investigators have not publicly linked Shields’s murder to his cooperation, but the timing of his killing shortly after he began speaking with authorities has prompted speculation.

Anyone with information about Shields’s death is asked to come forward.
