WINCHESTER, Va. – On Tuesday morning, the Winchester Police Department (WPD) arrested Nija Johnson, 18, in connection with the death of her six-month-old daughter.

“This morning, a Winchester grand jury indicted Johnson on second-degree murder charges in the death of her six-month-old daughter, Natalia,” Lauren Cummings, a spokesperson for the Police Department told WHAG shortly after police made the arrest.

Johnson’s indictment comes after a five-week investigation, which all started on January 20 in the 600-block of Sherlock Trace, when police responded to a call in reference to an infant suffering from cardiac arrest.

“Typically if there is a cardiac arrest in an infant, we would respond just to rule out any suspicious activity that might have occurred,” Cummings explained.

Police responded, and the infant, later identified as six-month-old Natalia, was flown to Inova Fairfax Hospital. Police said she died three days later on January 23rd.

Police immediately began investigating what could have caused the infant to go into cardiac arrest and die.

“Our investigation revealed that the mother actually caused the child’s death,” Cummings stated. “The investigation is ongoing, and those are the only details we are releasing at this time.”

According to Code of Virginia, Johnson is looking at five to forty years in prison for the charge of second-degree murder.

Johnson remains in the custody of Northwestern Regional Adult Detention Center
