"This happened August of last year, was about 1-2 in the morning when a 911 hang up call came in where all that was heard was screaming and swearing.
I was the closest unit, riding alone as my partner had been voluntold for another assignment that set of days, so when I got out into the area, I was initially waiting for backup however as I was walking up to the house, I heard several voices screaming.
Rushing up to the house, the first thing I noticed was blood.... everywhere. The floor, the walls, the door, all covered to shoulder height. A distraught woman screamed and pointed me towards the living room.
Once I get into the living room, I see a male and female on a couch, both covered in blood. The male had a massive laceration on his right forearm, and the female had taken a belt and snake wrapped it around his arm to try and stop the bleeding. Seeing how the belt was applied, I knew it wasn’t doing anything to stop the blood flow, so I pulled out my tourniquet and as I prepped it said to the guy “This is gonna hurt like hell, but it’ll stop the bleeding”
I applied the tourniquet just above the top of his bicep, and knew it was on properly when he told me his hand had started to go numb. It was at that point I noticed a second deep gash on his tricep that went down to the bone.
It took EMS about 15 minutes to get to the house, and the paramedic made it abundantly clear that had I not applied the tourniquet, the male would have bled out long before they were able to get there.
In the end, turns out the guy had come home drunk, and forgot his keys... climbed up to a second story window and punched his way into the house, with near deadly results."
