Tyesha Monique Green (Prince William County Police)

On Monday, county police announced that they have charged the mother, Tyesha Monique Green, 22, of Quail Run Lane in Manassas, with murder, abuse and neglect of a child in a case that “could have easily been prevented through proper care of the child,” said Officer Jonathan L. Perok, a police department spokesman.

On May 9, 2010, medical units and police responded to the 4500 block of Kingsley Road in Woodbridge after police had been called about an unresponsive child, according to a news release. Green told police she had been sleeping in the same bed as the child and woke up later that night to find him unresponsive, police say.

The child was later pronounced dead at an area hospital.

Police referred the death to the state medical examiner’s office. After investigating the condition of the child — who had suffered an untreated infection and little care since his birth — police charged Green with murder, child abuse and neglect after working with the Commonwealth’s Attorney office, according Perok and a police news release.

The investigation revealed several factors that lead to the child’s death — including lack of child care and no follow-up treatment for an infection, according to police. Green was also using marijuana and alcohol at the time of the boy’s death, according to a news release, and the boy was kept in an “unsafe sleeping environment.”

There was little reason to believe the boy should have died from his condition if treated properly, Perok said. “He was three months. Over those three months he was neglected to the point where he died,” he said.

A court date has not yet been scheduled.
