The Baltimore County Medical Examiner's office ruled that a 26-year-old intellectually disabled man died by homicide while in custody in Frederick.
The medical examiner ruled that Robert Saylor, of New Market, was asphyxiated and the manner of death is a homicide. He died on Jan. 12.
Saylor was at a movie theater with a health aide in Frederick on the night of the incident. He had just watched Zero Dark Thirty and refused to leave the theater after the film ended, authorities say.
Three deputies were called to handle the situation. Saylor was handcuffed and was allegedly resisting arrest when he had what authorities describe as a medical emergency.
According to a law enforcement source familiar with the case, the 26-year-old went into distress when he was put face down on the ground.
Deputies removed the handcuffs and took him to a hospital, where he was later declared deceased.
Last month ABC7 spoke with Saylor's mother, who was shocked by how her son died.
"He has never had anyone put their hands on him in their life," says Patti Saylor. "He would not have been doing anything threatening to anybody."
The three deputies involved in this case have been identified as Lt. Scott Jewell, Sgt. Rich Rochford and Deputy First Class James Harris. They are continuing to work their normal assignments.
Frederick authorities are continuing to investigate the incident.
