19 Year Old Student Hanged Herself In Her Room

19 year old 2nd year student was found hanging in her room at a boarding house, roughly 24 hours after she had last been heard from. When her parents could not reach her, her father and one of her friends went to the location and forcibly entered the apartment only to find that she had hanged herself with a bedsheet the day before. Several of her friends said she had been depressed about her student loans and about an illness her mother was suffering from.
The police report noted that the typical findings in a suicidal hanging were all present and that her feet were flat on the ground beside a stack of six plastic chairs, which she probably stepped off of after tying the sheet.
The police also informed reporters of the results of the visual examination: her tongue was swollen, protruding and bitten tightly between her teeth...the ligature mark matched the bed sheet noose...her fingers were curled inward...and she was doubly incontinent in death, with urine and feces being present in her trousers.
They also indicated that there was blood on and beneath both of her feet. The reason for this was not explicitly stated, but the family was concerned enough about it to order a formal autopsy (which is very uncommon in clear suicide cases due to cost).
What is up with the blood? It could be one of several things. She's been dead an entire day. Could be decomp drainage from her anus or genitals or possibly even from her feet if blood has pooled and thickened there long enough to split the skin under her toenails, which I have seen before. But all of the visible tissue above her ankles looks whole and undamaged. Bit of livor, but no sloughing or blebs or ruptures.
