1: they observed multiple empty wine bottles and that the water was hotter than regular. Their bodies were on the bottom of the tub, they had been dead for awhile. The paramedics noticed that the Underhills had a very nice two-story mansion. As they went to the back patio, they saw empty bottles. One of the paramedics, Kavita Dickson, was the first to notice the Underhills underwater in the hot tub. As she climbed in to bring them to surface, she felt how hot the water in the hot tub was. The Underhills were dead for quite a while before the paramedics arrived.
2: did they take medication prior to death? Medical History? What temperature do they normally keep the hot tub at? ALCOHOLISM? Kavita seemed surprised by the temperature of the water, so she was obviously questioning why the temperature was so high.

They should have asked her about their drinking habits, what medications they were on, if they had any health conditions, what their medical histories were, how often they used the hot tub, and how hot they normally kept its temperature.
3: the lasik that he took would most likely be affected by the copious amounts of alcohol. The higher than normal heat should be taken into account. The heat would raise heart rate and they had a stressful day to amplify this.

The Lasix could have caused some adverse reaction relating to extreme dehydration. The abnormally high heat in the hot tub may have also played a role
4: the high blood pressure and heart rate would contribute to a potential heart attack. The combination of lasix N
