Homicide in the dental chair?

ANTIOCH, Calif. -- The Sacramento County Coroner has ruled the death of a 3-year-old while he was undergoing a dental procedure a homicide. The California Dental Board and the district attorney are now investigating the circumstances of how the boy died last summer in the Delta-area dental office. A dentist who conducted the procedure, William Martin Nielsen, has been practicing and treating patients at his Antioch office during the six months since the death of 3-year-old Rogelio Campos-Crespo, of Brentwood According to authorities, the little boy was being prepped to have crowns placed on decaying teeth, when something went wrong. The Sacramento County Coroner's report says that "the decedent's nose and mouth were covered by the dentist's hand to calm him, while a 4-by-4 gauze pad or sponge ... was left behind in the mouth," which caused him to smother and likely choke on the gauze pad during the dental procedure. The pad had been left behind in the mouth and acted as a gag, according to the report.

*** The dentist is holding his hand over the kid's mouth to "calm him down" as he is sitting there fighting for life?!?!?! Oh my goodness!!
