Cause of death

According to a criminal complaint, Mitchell ambushed outside the Hyatt Regency hotel, ran inside and refused to leave. All four men charged with murder rolled the 43-year-old onto his stomach as they tried to detain him.

Prosecutors said the prone position restricted Mitchell’s breathing and caused his death. The medical examiner said Mitchell was morbidly obese, had cocaine and meth in his system and heart disease – and that Mitchell could have died in that prone position even if no one had used force.

Additional fees?

A lawyer for Mitchell’s widow said a hotel employee who hit Mitchell with a broom and a guest involved in the incident should be charged with assault.

“There are undoubtedly others who were involved in Mr. Mitchell’s assault,” attorney William Sulton said Thursday.
