Tj Martineau Sexually assaulted my son Massachusetts

For an EMS, this man is as bad as they come and I've experienced my fair share of emergencies and first aid responders. He was just off putting from the very get go, and it wasn't the attitude needed for such a medical emergency that my son and I were experiencing. My biggest problem was my son felt sexually assaulted, something he told me of after the entire fiasco. He grabbed my son's buttocks while helping him up into the ambulance. Apparently he grabbed his left forearm and as he was climbing up into the ambulance, he placed his hand on his buttocks concealing the act of grabbing my seventeen year old son's buttocks as a act of "helping him up" into the ambulance. At the time I was looking away talking to the fireman finishing up with them, then got into the ambulance with my son. I did notice him being very hands on with my son during the entire time we were in the ambulance, buy didn't think too much of it. I was more put off by how rude he was but come to find out that it was due to my son telling him off for grabbing his buttocks prior to me getting into the ambulance. In any regard the events are perplexing that he feels it's appropriate to act in such a dispicable manner.
