In an upscale penthouse on the 18th floor of a luxury high-rise

In an upscale penthouse on the 18th floor of a luxury high-rise, Jonathan Cruz, a wealthy 45-year-old person, is found murdered, lying face down near a shattered glass coffee table, having suffered a fatal blow to the head from a bronze sculpture nearby. Half of his body is naked, and half is covered in white sheet. The scene suggests a struggle, with a chair knocked over, a torn curtain, and scattered papers. Clues include a small torn note in the victim's clenched hand, three different sized bloody handprints on the floor, a clean stacked books on the floor, and an a woman's underwear beside it.
