I wouldnt care if you removed compression of neck as its redundant to chokehold and during physical restraint by police as it is probably unnecessary but I dont think prone positioning should be removed And Im not sure if poor health is needed as it was only a contributing condition rather than a primary cause I dont see how it could be simplified much more If I remember right contributing causes of death are called contributing if the death would likely have occurred even if those causes hadnt be present Thus it may not be accurate to blend the two categories together under causes of death It might be best to add a contributing conditions section to the info box if that were to be included Id probably just leave it as is though since it is not excessively long Having the quotes in the info box is probably unusual but I dont see anything wrong with it and they dont take up significant room and they are useful info to the reader
