It is rare for medical workers to wear multiple gloves unless in the operating room in cases of known or possible/suspected communicable diseases or when implants are being placed. Even still the gloves worn are by the surgeon, scrub techs and any assistants (not the rest of the staff) and are thin, tight surgical gloves. Generally, the staff will wear scrubs and likely a jacket +/- an undershirt, which is not much different than normal people in a cool workplace. They don personal protective equipment (PPE) like plastic or paper fabric gowns over clothing/scrubs for interactions with patients that have easily communicable infections (like C. diff) and then remove the PPE upon exiting the room so that they don't transmit infections to other patients. It's not the norm to just walk around with all this gear on. While of course it's possible that the abductor was a healthcare worker, respectfully, wearing multiple layers is no more likely to make the suspect a healthcare worker than a snowboarder. He could've been wearing a full body bunny suit under pants and a hoodie for all we know and workers of clean room fabrication labs are more likely to be used to wearing that attire. Also, healthcare workers tend to reflexively cover bleeding wounds and hold pressure.
