In unguarded, taped interviews with his defense attorney, Wendy Patrickus, Jeffrey Dahmer explicitly stated that he had sex with his victims before and after their deaths. He explained that he wanted to remain with the person as long as possible, preserving some of his victims selected organs, skeletal tissue and bones. Ted Bundy
Ted Bundy (1946–1989) was an American serial killer who raped and murdered at least 30 young women during the 1970s. He also confessed to participating in necrophilic acts, claiming to have chosen secluded disposal sites for his victims bodies specifically for post-mortem sexual intercourse. Karen Greenlee
In 1987, Karen Greenlee gave a detailed interview called “The Unrepentant Necrophile” for Jim Mortons (edited by Adam Parafrey) book Apocalypse Culture. In this interview, she stated that she had a preference for younger men and was attracted to the smell of blood and death. She considered necrophilia an addiction. The interview was held in her apartment, which was apparently a small studio filled with books, necrophilic drawings, and satanic adornments. She also had written a confession letter in which she claimed to have abused 20–40 male corpses. Dennis Nilsen
Dennis Nilsen (1945–2018) was a Scottish serial killer who had developed an association between death and intimacy, later finding posing as a corpse a source of sexual arousal. In 1978, Nilsen committed his first murder and had intercourse with the victims corpse, keeping the body for months before disposal. Nilsen was reported to have sexually abused the corpses of various victims until his arrest.
In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", plural: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly. It articulates with the clavicle (collar bone) to form the acromioclavicular joint. Structure
The acromion forms the summit of the shoulder, and is a large, somewhat triangular or oblong process, flattened from behind forward, projecting at first lateralward, and then curving forward and upward, so as to overhang the glenoid fossa. It starts from the base of acromion which marks its projecting point emerging from the spine of scapula. Surfaces
Its superior surface, directed upward, backward, and lateralward, is convex, rough, and gives attachment to some fibers of the deltoideus, and in the rest of its extent is subcutaneous. Its inferior surface is smooth and concave. Borders
Its lateral border is thick and irregular, and presents three or four tubercles for the tendinous origins of the deltoid. Its medial border, shorter than the lateral, is concave, gives attachment to a portion of the trapezius, and presents about its center a small oval surface for articulation with the acromial end of the clavicle. Variation
There are three morphologically distinct types of acromia and a correlation between these morphologies and rotator cuff tear:

Os acromiale
The acromion has four ossification centers called (from tip to base) pre-acromion, meso-acromion, meta-acromion, and basi-acromion.
