Helen Valentine was found deceased in the master bedroom of her upstairs, two-bedroom apartment, at 11:58 AM on Tuesday morning. Upon arrival, the investigators noticed an empty bottle of vodka on the floor of her bedroom, and two shot glasses- half-full with vodka, on the kitchen table. There were also three visible dust footprints on the linoleum floor in the bathroom and kitchen. The television was on and the refrigerator was slightly ajar. Some half-eaten cheese and crackers were located on the countertops in the kitchen, and the smell of bleach was very apparent in the kitchen. Valentine was found in a prone position, completely nude, with her head towards the foot post of her bed, facing the wall. Valentine's entire apartment was a mess, but there does not seem to be any real signs of struggle. Investigators noticed a few cuts and bruises on Valentine's wrist. After closer examination, investigators noticed a small gunshot wound on her left temple. The weapon was found in very close proximity to Valentine's right side, next to her right shoulder.The three windows to Valentine's apartment were open and the front door was unlocked. Neighbors provided statements, stating that Valentine was a nudist and liked to flash people who passed by her windows. Investigators also found an apparent suicide note on the computer screen in the second bedroom (the computer was still on, but was in hibernating mode). Valentine's bank check; made out for $1,006.57 to a nudist colony resort and spa, lay on her computer desk.In the investigator's initial inspection, blood could be seen in the second bedroom and on the windowsill of one Valentine's apartment windows.
