A Frederick County grand jury declined to indict three sheriff's deputies who attempted to remove a man with Down syndrome from a movie theater, leading to his asphyxiation death.

The three deputies restrained and handcuffed Robert Ethan Saylor, 20, in a Frederick movie theater on Jan. 12. An autopsy showed that Saylor died of asphyxia but suffered from other conditions including obesity and heart disease, according to State's Attorney J. Charles Smith. The autopsy also said Saylor had "anger issues."

Smith also said that the jury made their decision after hearing from 17 eyewitnesses and the three sheriff's deputies, who were working as mall security officers at the time of the incident.

Saylor's parents will review the documents from the investigation before deciding whether to pursue civil action, according to their attorney.
